The directors of the HR department of a medium sized company have asked you to obtain answers to several questions about the health and well-being of men in mid-life or older in your company and write a report. You have access to a survey of a sample of 1297 male employees aged 39 and over that has recently been carried out (hals.sav). The questions you need to answer are:
1. What is the age distribution of men? (Use, for example, Histogram)
2. What proportion of men belong to each category of own health (OWNH)? (Use, for example, Pie Chart)
3. What is the average height and weight of the men? (Use, for example, Descriptive Statistics, Descriptives)
4. How is lung function (HYFEV) related to age, if at all? (Use, for example, Linear Regression)
5. How different are the average FEVs (i.e. lung functions) of the different social class categories? (Use, for example, One-way ANOVA)
6. Is there a significant difference between the proportion of smokers and non-smokers who have poor mental health state? (Use, for example, Chi-Squared)
In your report, present your findings and, most importantly, explain to your HR directors what these analyses mean. Assume that the directors do not know much about statistics.
Advantages of Wi-Fi | Essay Distributed: 23rd March, 2015 Last Edited: eleventh December, 2017 Disclaimer: This article has been put together by an understudy.

Wi-fi and the Development of Multimedia 1. Presentation In mid 1990s, the advancement of media transmission innovation enter new period, as Internet ends up appealing administrations that assistance clients or clients to acquire data that put away in a PC in any piece of the world. In Telecommunications and Computers, James Martin clarifies there is cozy connection amongst PC and media transmission. While media transmission innovation accentuates the part of foundation or equipment in correspondences, the improvement of PC manages substance that assume a noteworthy part in the present propelled interchanges in every single human action like saving money, producing plan, and furthermore at home. The utilization of media transmission and PCs instantly forms into the term data innovation that turns into a renowned language in the present refined data time. In partnerships, the utilization of data innovation is obligatory since it improves employments achievement and kills superfluous costs (Ferguson, 2000). One of creation in media transmission innovation that draws in consideration is Wi-Fi (Wireless Fidelity). This alludes to remote innovation guidelines that help fast remote systems administration or WLAN that stands for Wireless Local Area Network. The innovation standard depends on the plan suggested by IEEE 802.11. The present advancement has been on 802.16 g standard. The advancement of every standard enhances the scope and information rate (Stuart, 2007). The main advancement of Wi-Fi innovation expects to give contrasting option to Local Area Network (LAN) yet current improvement Wi-Fi is additionally mainstream media for getting to Internet content from different sorts of Wi-Fi empowered contraptions. Concerning data innovation utilizes, this paper will talk about the effect of Wi-Fi on sight and sound. The exchange incorporates the thinking like costs contemplations of Wi-Fi usage, speedier access, and broad topographical scope. With a specific end goal to give useful data, this paper will utilize the outline WLAN that associate with numerous sorts of sight and sound substance and gadgets. 2. Mixed media By definition, mixed media (Lat. Multum + Medium) alludes to assortment types of data (video, sound, pictures, content, intuitiveness, and activity) that created keeping in mind the end goal to educate or engage group of onlookers. These days, devices that have interactive media ability imply that they can store or plays the above types of data, for example, a few sorts of phones, individual computerized collaborators (PDAs), work area PC etcetera. 3. Focal points of Wireless Fidelity (Wi-Fi) 3.1 Cheaper than other web gadgets Dissimilar to other transmission alternatives (link, satellite, and microwave radio), Wi-Fi is more affordable bases on cost of Wi-Fi empowered items/terminal, organize set up, and expandability. As far as setting Wi-Fi organize, for occasions, a client only place the Wi-Fi get to point at that point set up the terminals as long as it covers by the Wi-Fi signals. This Wi-Fi execution is along these lines significantly more less expensive since it doesn't requires broad works dissimilar to occurs in setting link based or satellite-base systems (Stuart, 2007). Furthermore, cost of Wi-Fi empowered terminals is lower than microwave radio or satellite CPE (client commence gear). For examples, cost of WLAN connector is under $35 each while microwave radio may costs $5,00 for one band of point-to-multipoint (PTMP) radio. In the mean time, expenses of ground portion of satellite framework that makes out of radio wire dish, modem, electrical supplies (control enhancer, rectifier, and cabling) and common works may reach $20,000. The less expensive execution of Wi-Fi benefit is upheld by numerous sorts of Wi-Fi empowered terminals like printers, PCs, and smart phones driven the economies of size of delivering such Wi-Fi innovation (Figure 1). Figure 1 Wi-Fi empowered terminals Source: http://www.npwireless.com/I/elip/elip-wifi.jpg 3.2 Faster than most remote gadgets/framework Another advantage of executing Wi-Fi benefit is that it offers clients speedier speed than link - based framework (bent combine or coaxial link). For WLAN and web get to reason, the utilization of Wi-Fi is additionally speedier than DSL (advanced endorser line) association (Stuart, 2007). Figure 1 Data Rate Comparison of Some Wireless Acces Technology Source: http://ethernet.industrial-networking.com/pictures/art_images/ieb34wirelessnet4.gif Commonplace ADSL (nonconcurrent computerized buy in line) administration can offer information rate up to 384 Kbps while Wi-FI can give up to 54 Mbps and 100 Mbps relying upon models as appeared in the Figure 1. The quick information rate of Wi-Fi empowers the speedier transmission of sight and sound substance. Figure 2 demonstrates ordinary speed necessity of a few applications. It implies that Wi-Fi with accelerate to 100 Mbps can convey a wide range of sight and sound substance like video conferencing and even Digital TV. This advantage underlies a few system suppliers/media transmission organizations to convey their administrations by utilizing Wi-Fi. Figure 2 Multimedia Applications and Data Rate Requirement Source: http://www.plannedapproach.com/pictures/image002.gif 3.3 Better land scope The advantage of any remote administrations is it can achieve any area as long as inside the flag scope notwithstanding the scene and building model. Strikingly, the basic set up of Wi-Fi arrange (called problem areas) causes the innovation is generally accessible in nearly place of interests like shopping centers, eateries, airplane terminals, book shops, cafã©, fast-food eateries, etcetera. In the U.S. alone, as indicated by IDC investigate in 2003, the development of Wi-Fi hotspots were around 57% every year inside the following five year till 2008 (Stuart, 2007). The immense accessibility of Wi-Fi hotspots is likewise moved down by the scope that remote access point can reach. Regularly, in open air zone, Wi-Fi can reach as long as a couple of hundreds meters while in indoor region, it can achieve 25 to 50 meters contingent upon solid materials, control, radio recurrence, Wi-Fi contraptions affectability, and different obstacles. 4. Conclusion This paper has talked about the definition, advantages, and usage of Wi-Fi (Wireless Fidelity). The three advantages of Wi-Fi innovation (less expensive expenses of usage, quicker information rate, and better land scope) turn into the basic purposes for the broad utilization of Wi-Fi for conveying media substance. This is on the grounds that interactive media substance like video conferencing, messages, video spilling, and multiplayer recreations that conveyed through Internet require fast information transmission that Wi-Fi can give.>GET ANSWER
