In , Addison Group and Kelton surveyed the work preferences and attitudes of working adults spread over three generations — Baby Boomers, Generation X, and Millennials (Society for Human Resource Management website). One question asked individuals if they would leave their current job to make more money at another job. The file Millennials contains the sample data, which is also summarized in the following table. Click on the datafile logo to reference the data. Generation Leave Job for More Money? Baby Boomer Generation X Millennial Yes 137 171 175 No 213 199 186 Conduct a test of independence to determine whether interest in leaving a current job for more money is independent of employee generation. Compute the value of the test statistic (to decimals). Do not round your intermediate calculation. What is the -value? Use Table 3 of Appendix B. The -value is . Using a level of significance, what is your conclusion? Conclude interest in leaving job for more money independent of the…
Thirty-five percent of all Americans drink bottled water more than once a week (Natural resources Defense Council, December 4, 2015). Suppose you have been hired by the Natural Resources Defence Council to investigate bottled water consumption in St. Paul. You plan to select a sample of St. Paulites to estimate the proportion who drink bottled water more than once a week. Assume the popluation proportion of St. Paulites who drink bottled water more than once a week is 0.35 , the same as the overall proportion of Americans who drink bottled water more than once a week. Suppose you select a sample of 540 St. Paulites. Show the sampling distribution of “p with a line over it” (to 4 decimals). E(p with a line over it) = 0` p with a line over it = Based upon a sample of 540 St. Paulites, what is the probability that the sample proportion will be within 0.08 of the population proportion (to 4 decimals). Probability = Suppose you select a sample of 190 St. Paulites. Show the sampling…
New York State has approximately 250,000 employees across over 70 state agencies, commissions and boards, ranging in size from approximately 50 to over 5,000 employees. Assume that you wanted to draw a representative sample of 1,000 New York State employees. Describe two ways that you could draw such a sample and briefly describe the advantages and disadvantages of each of these sampling approaches.

Thirty-seven percent of all Americans drink bottled water more than once a week (Natural resources Defense Council, December 4, 2015). Suppose you have been hired by the Natural Resources Defence Council to investigate bottled water consumption in St. Paul. You plan to select a sample of St. Paulites to estimate the proportion who drink bottled water more than once a week. Assume the popluation proportion of St. Paulites who drink bottled water more than once a week is 0.37, the same as the overall proportion of Americans who drink bottled water more than once a week.

Give an science, medical, epidemiology or public health sample case of quota sampling.
Sociologists argued that women on average earn less than men as women often choose to work less hours. They further suggest that the choice of hours worked may be driven by various factors such as age, childcare needs, occupation choice and flexibility. To investigate the relation between hours worked and income earned by Australian men and women, a researcher plans to survey a sample of individuals across the country. a) What type of survey method the researcher could use and why? b) What sampling method could the researcher use to select his/her sample and why?
There are 4327 colleges in a certain country and the number full-time students is 13, 287,563. (a) Are the numbers of full-time students at different colleges discrete or continuous?

(c) If we randomly select four colleges and survey all their full-time students, what type of sample is obtained? (random, systematic, convenience, stratified, cluster)
Sociologists argued that women on average earn less than men as women often choose to work less hours. They further suggest that the choice of hours worked may be driven by various factors such as age, childcare needs, occupation choice and flexibility. To investigate the relation between hours worked and income earned by Australian men and women, a researcher plans to survey a sample of individuals across the country. Briefly explain a) What type of survey method the researcher could use and why? b) What sampling method could the researcher use to select his/her sample and why? c) What are the two main variables the researcher should consider collecting data for the purpose of the above analysis and why? Identify the data type(s) for the variables. d) What kind of issues the researcher may face in this data collection?
