Several years ago, two companies merged. One of the concerns after the merger was the increasing burden of retirement expenditures. An effort was made to encourage employees to participate in the 401(k) accounts. Nationwide, 62% of eligible workers participated in these accounts. The accompanying data table contains responses of 30 employees of the company when asked if they were currently participating in a 401(k) account. Complete parts a through d. Click the icon to view the data table. a. Determine the sample proportion of company workers who participate in 401(k) accounts. The sample proportion is (Round to three decimal places as needed.) b. Determine the sampling error if in reality the company workers have the same proportion of participants in 401(k) accounts as does the rest of the nation. The error is. (Round to three decimal places as needed.) c. Determine the probability that a sample proportion at least as large as that obtained in the sample would be obtained if the…

You discovered a program for sales personnel that supposedly improve interpersonal skills and thus help settle deals with customers more often. You decide to send8 of your sales people for the training, and compare the amount they brought in sales in the month before they went and in the month after they received the training. The data are:Xbefore: 400, 300, 1200, 2100, 700, 450, 650, 3400Xafter: 1000, 400, 1000, 2500, 1200, 600, 800, 3000 C. Calculate 95% confidence intervals for the estimate of the difference.

An epidemiologists is studying two populations that have recently had an outbreak of a disease with similar symptoms. In one population of 600 people, 450 of them became infected and 3 of them died. In the other population of 200 people, 20 were infected and 10 died. Did the two towns have an outbreak of the same disease? Defend your answer. Use prevalence and mortality rates to help you.

After the rule change between 2006 and 2007 that permitted teams to prepare their own footballs, new fumble statistics were accumulated for the 8 years from 2007 thru 2014. Once again, the average fumbles per touch for each of 23 teams during this time period are given below: The numbers are the actual numbers. They are not just invented for this assignment. 36,38,40,40,44,44,44,44,46,46,46,46,48,48,48,48,50,50,50,52,52,56,74. During the 2007-2014 period, the New England Patriots fumbled the ball one time for every 74 touches. Conduct a z-test that tests whether it is reasonable to think that the Patriots had no particular competitive advantage on fumbling during the time period 2007-2014.
