click on “student edition”, go to cases and click on “Campbell-Ewald Pumps Awareness into the American Heart Association case”. Then, once you have read the case answer questions 2 and 3 from the case. Answer the questions in APA style.
Assume the following:
2.1. A lakefront resort is planning for its summer busy season. It wishes to estimate with 95% confidence the average number of nights each guest will stay for a consecutive visit. Using a sample of guests who stayed last year, the average number of nights per guest is calculated at 5 nights. The standard deviation of the sample is 1.5 nights. The size of the sample used is 120 guests and the resort desires a precision of plus or minus .5 nights. What is the standard error of the mean in the lakefront resort example? Within what range below can the resort expect with 95% confidence for the true population means to fall? Show the calculation; otherwise, the answer will not be accepted.
2.2. A local restaurant is planning a study on demand for meals over holiday weekends. In calculating the desired sample size for the study, the restaurant’s researcher decides to use a rule-of-thumb calculation for estimating the population dispersion. If the range of meals in the study is 0 to 30, what standard deviation does the rule-of-thumb method produce? Show the calculation; otherwise, the answer will not be accepted.
2.3. A microbrewery plans to conduct a study on beer consumption among men between the ages of 29 and 45. A pilot test indicated that men in this age category consume an average of 6 beers per week with a standard deviation of 2.3. If the microbrewery seeks a 95% confidence level and a precision of .5 beers, what size sample should be used in the study? Show the calculation; otherwise, the answer will not be accepted.
Sample Solution
For centuries the argument of free will and determinism has been the ongoing great debate. Between a philosophical and scientific stance there have been many debates as to which notion upholds truth and abides by the laws of nature; determinism or free will. Free will is the concept that we as conscious human beings have the ability to freely and genuinely make undetermined choices in situations where we are free to do so. The opposing view to this, determinism, is the notion that all events in the world are effects or outcomes of previous events. In this essay I will briefly explain both notions as well the varieties behind both them. I will give a brief overview of the scientific and philosophical approaches to the notion of free will. If determinism is true then the concept of human morality is merely an illusion of choice. Therefore, free will is the most sensible in the case of human beings because as we are aware of our free will or our ability to choose and this makes us responsible for moral actions and all other acts as human beings. Determinism is the notion that all things are determined by previous events. It is closely related with the domino effect; as one domino falls the next will fall and so on and so forth. This closed universal view means that there everything is predetermined and predestined to happen leaving no room for anything new to come into existence. Every action, thought or conscious decision that we make as a human is the effect of our previous action. In a greater sense, all events that have happened in history are effects of prior events. This leads one to believe that all things are concrete and unalterable in past, present or future. Determinism is a far reaching and radical notion that affects streaming beliefs such as morality, science and religion. Contemporary scientists have taken on the relative issue of human freedom by linking determinism and genetics through genetic determinism. This notion links determinism directly to DNA and the gene expression of a human. Gene determinism is supported by the idea that because of mishaps with certain genes it can lead to physical and mental alterations which means that we ar>
