When the results of a survey or poll are published, the sample size and the margin of error should both be given. For example 1000 voters were surveyed and 39±2% of the voters agree with the president. In this example, N=1000 and the margin of error (MoE) is 2%.
This website lists several public opinion polls. Search the site and find a poll where the sample size and margin of error are given. Try to find a poll dealing with a topic in your profession or one in which you are really interested.
Main Post: Determine the following information for the selected poll results and include in your initial post. See Example and DB starter video in Unit 6 LiveBinder.
1. URL for the website. State the poll question, the sample size n, and the margin of error (also known as sampling error).
2. Interpret the results of your poll using your own words and full sentences. Note: Depending on the question asked, your poll may have more than one poll result – you only need to discuss one result.
3. State the confidence interval using the MoE. What does this confidence interval estimate?
4. Use the Confidence Interval template https://youtu.be/vHXLZ0RfU1E to calculate the confidence interval based on the sample size and the number of successes (the proportion you are interested in). Use a confidence level of 95%.
5. What is the calculated confidence interval? How does this compare to the interval in part 3 using the poll’s margin of error?
6. Discuss potential biases that could skew sampling results.

Hypothesis testing typically begins with a theory, a claim, or an assertion about a particular parameter (mean, μ, or proportion, p) of a population.
The Federal Trade Commission (FTC) is an independent agency of the U.S. federal government charged with preventing unfair or deceptive trade practices. It regulates advertising, marketing, and consumer credit practices, and also prevents antitrust agreements and other unfair practices.
The FTC publishes press releases regularly about health and fitness claims athttps://www.ftc.gov/news-events/media-resources/truth-advertising/health-claims
Main Post: Find a claim about a product or service from one of the press releases listed in the FTC website. Read through these and select one of interest to you that has not been picked by anyone else yet in class. See Example and DB starter video in https://youtu.be/R3AozFRuLWE
1) Summarize the advertising claim as shared in the media. What population parameter (mean, μ, or proportion, p) is the claim about?
2) If you were to formulate a hypothesis test about this product/service, what would your null and alternative hypothesis be? (Be sure to use all the correct notations for H0 and Ha)
3) State whether you have a one-tailed lower, one-tailed upper, or two-tailed test (Be sure you use the correct inequality signs).
Environmental change has been talked about since more than 200 years prior however has just picked up pertinence and been considered important in the 1950s (Harding, 2007). As states come to understand the conceivable awful results of worldwide environmental change and endeavor to handle it by actualizing certain approaches, they are constantly stood up to with a quandary. To organize environmental change, states would need to lessen their emphasis on financial advancement, in any event in the short run. Many are reluctant to do as such for dread that intra-generational imbalances would be exacerbated (Heil and Selden, 2001). Notwithstanding, we trust that environmental change ought to in reality be organized over financial improvement as atmosphere alleviation empowers both intra and between generational disparities to be tended to simultaneously. Alternately, we probably won't accomplish the equivalent if we somehow happened to organize financial advancement over environmental change. It has been contended that the best way to lessen salary uniqueness is to advance further financial development. Tragically, this determined spotlight on enhancing a nation's worldwide monetary standing has brought about substantial inconsistencies between the rich and poor, be it inside or between countries. This is on the grounds that rich nations can bear to put resources into apparatus and work to expand yield and seize pieces of the overall industry while poorer nations miss out in such relative favorable position. Anyway by assuming responsibility of environmental change, this disparity can be reduced. To begin off, natural farming could be embraced as an atmosphere alleviation procedure. The different cultivating frameworks utilized in natural agribusiness can expand pay sources and decrease the susceptibilities of horticulture to effects of maladies and environmental change, for example, higher frequencies of dry spells or flooding. Furthermore, it can enhance soil water ingestion and maintenance limit which diminishes soil disintegration. Therefore, less CO2 and N2O would be produced from less soil disintegration and the non-use of hurtful cultivating framework inputs – composts and pesticides (Muller, 2009). This exertion can be additionally upheld by execution of unhindered commerce developments (Carter, 2007), which empowers purchasers to purchase items specifically from the makers in less created nations. This wipes out income to go betweens and permits littler ranches from less created nations to win higher livelihoods. Not exclusively are we moderating environmental change by empowering all the more ecologically cordial strategies for cultivating, we are entirely permitting makers, who might somehow or another be burdened because of their failure to increase similar favorable position, manage their business. Subsequently, handling environmental change would permit to address both environmental change and financial imbalances simultaneously which we would not have the capacity to accomplish should we just spotlight on financial advancement. In addition, seeking after financial improvement would wind up counterproductive if the results of environmental change, which will impede financial advancement, are neglected. One progressively articulated result is sea fermentation – the take-up of carbon dioxide in the seas. This marvel decreases shellfishes' capacities to shape their carbonated shells and in this way brings down their survivability (Fabry et al, 2008; Holman et al, 2004). These antagonistic impacts are in this way meant monetary misfortunes in our marine fisheries which depend intensely on the harvests of these monetarily profitable marine living beings (Gazeau et al, 2007). Likewise, these impacts joined with a worldwide temperature alteration are harming and blanching the reef-building corals which are homes to astounding quantities of marine creatures (Phinney et al, 2006, Lumsden et al, 2007). With their vanishing, the productivities of fisheries are additionally diminished. For urban areas like New Bedford which depends significantly on fisheries incomes, the income misfortunes would unfavorably modify its principle monetary exercises and socioeconomics, and exacerbate pay inconsistencies (Cooley and Doney, 2009) Coral reefs additionally give beach front assurance (Moberg and Folke, 1999) which support a portion of the most elevated worldwide populace densities and poorer populaces situated at the waterfront areas from getting to be ecological exiles of characteristic disasters (Shi and Singh, 2003). Also, seriousness and recurrence of cataclysmic events, for example, dry spells and surges have expanded because of changing climate designs, leaving Small island Developing states (SIDS) and slightest created nations (LDCs) to a great degree vulnerable to huge financial misfortunes in profitability and consumptions in recuperation (Office of the High Representative for the Least Developed Countries, Landlocked Developing Countries and Small Island Developing States, 2009). Besides, changes in precipitation examples and temperature rise may likewise adjust current land use for nourishment crops, bringing about novel plant pathogen or irritation issues. This could possibly diminish worldwide sustenance supplies (Cannon, 1998; Coakley et al., 1999; Parker and Gilbert, 2004) and exacerbate starvations in creating nations. The temperature rise additionally empowers the spread of jungle fever and different maladies bringing about critical medical issues. Subsequently, the results of environmental change would impede countries from accomplishing financial improvement on the off chance that one doesn't approach financial advancement in light of environmental change. By organizing financial advancement for the sake of lightening intra-generational imbalances, we are then overlooking another type of similarly essential disparity and it is none other than between generational disparities. As good and sound people, we have the ability to prepare and identify with others. Subsequently, since we can anticipate the conceivable fate of our relatives and feel for their predicament, we should follow up on environmental change instead of essentially consider satisfying our own present needs and denying them of their future needs. There is adequate and solid proof that the globe is confronting extreme consumption in vitality delivering assets (Hartmann, 2004). Besides, our unpredictable utilization of Earth's assets is adding to environmental change at a disturbing rate (Halsnaes, 1996). People living in Europe and Asia started consuming coal for utilization after they uncovered it roughly 900 years prior. This denoted the beginning of people's utilization of old daylight, or, in other words amid old occasions, or around 400 million years prior. Afterward, people likewise uncovered oil and it exponentially expanded our capacity to support life and expend when contrasted with previously, where we could just get by on current daylight, that is, vitality put away in plants (Hartmann, 2004). These revelations are especially huge for mankind as it is using antiquated daylight to maintain life that we can modify the earth for our different employments. From that point forward, we have possessed the capacity to create more garments and nourishment. This is on account of a considerable measure of land that ought to have been utilized to trap current daylight has now been changed over for different purposes, for example, mass developing of cotton and sustenance crops. The majority of this would not have been conceivable if people had not found antiquated daylight that they could tap on (Hartmann, 2004). People's capacity to maintain life developed drastically thus did the human populace as far as its sheer number. As indicated by Hartmann, "In under a tenth of a percent of the aggregate history of mankind, we have encountered more than 90 percent of the aggregate development of the human populace" (2004). Be that as it may, these limited assets would one day be exhausted. Sources collectively concur that the oil supply is depleting at an extraordinary rate. In 1996, oil industry specialists anticipated that we have just a "very nearly" 45-year-supply of oil left. Different specialists in the business are way less idealistic. Besides, because of quickened populace development in the Asia's creating nations, worldwide vitality request is relied upon to twofold by 2020 (Hartmann, 2004). Should we lose this essential wellspring of vitality, we hazard having seven billion starve in the 2050 (Hartmann, 2004). This features how critical the circumstance is and how basic it is for us to address the issue. On the off chance that we were to just organize financial improvement, there is no motivating force for us to diminish our utilization of these assets. In actuality, we may wind up conceiving strategies to all the more likely tap on them to increment monetary development. Nonetheless, should we choose to put environmental change at the fore, we would definitely need to lessen our oil and coal utilization since utilizing them would just add to environmental change (Le Quéré et al., 2012). At the end of the day, we would address two issues just by giving one consideration. While the facts confirm that intra-generational imbalances are serious right now, between generational disparities would be also in the event that we neglect to address the issue of exhausting assets and environmental change. It unquestionably would not be reasonable for us to leave a globe that our future ages would not have the capacity to appreciate living in with all the staggering climatic conditions and absence of assets. In this way, environmental change ought to be organized over financial improvement before it is past the point of no return for us to. Financial advancement is certainly a critical objective for all countries. Be that as it may, on the off chance that we disregard environmental change and keep on utilizing our assets in an unsustainable way, the potential annihilation of nature and exhausted assets would keep us from advancing in accomplishing financial improvement for the present and what's to come. It is consequently basic that countries team up and submit themselves in alleviating environmental change. As said by Pew Center (2002), "Atmosphere relief isn't the objective, but instead an outgrowth of endeavors driven by financial, security, or neighborhood natural concerns.">GET ANSWER
