A study on the personality characteristics of drug dealers sampled 100 convicted drug dealers and scored them each on the Wanting Recognition? (WR) Scale, which provides a quantitative measure of a? person's need for approval and sensitivity to social situations.? (Higher scores indicate a greater need for? approval.) The sample of drug dealers had a mean WR score of 52?, with a standard deviation of 4. Use this information to find an interval estimate of the mean WR score for all convicted drug dealers. Use a confidence level of 90?%. Interpret the result.a.) The 90?% confidence interval for mean WR score indicates that the true mean WR score for convicted drug dealers is between ___ and ___ with 90% confidence.b.) The 90?% confidence interval for mean WR score indicates that 90?% of convicted drug dealers have a WR score between ___ and ___ .c.) The 90?% confidence interval for mean WR score indicates that the true mean WR score for all drug dealers is between ___ and ___ with 90% confidence.d.) The 90?% confidence interval for mean WR score indicates that 90?% of all drug dealers have a WR score between ___ and ___ .

Jane and Jill want their mom to ride the rollercoaster with them, but she thinks it will be too fast. She asks the girls to find out how fast the rollercoaster will be travelling. They find out that the speed of the rollercoaster, in miles per hour, is modeled by the function g(x) = x4 − 4x2 + 7x − 8, where x is time measured in seconds. How fast is the rollercoaster travelling at 2 seconds?

Jobs and productivity! How do banks rate? One way to answer this question is to examine annual profits per employee. Forbes Top Companies, edited by J. T. Davis (John Wiley & Sons), gave the following data about annual profits per employee (in units of one thousand dollars per employee) for representative companies in financial services. Companies such as Wells Fargo, First Bank System, Key Banks, Norwest Banks, and so on were included.42.9 43.8 48.2 60.6 54.9 55.1 52.9 54.9 42.5 33.0 33.6 36.9 27.0 47.1 33.8 28.1 28.5 29.1 36.5 36.1 26.9 27.8 28.8 29.3 31.5 31.7 31.1 38.0 32.0 31.7 32.9 23.1 54.9 43.8 36.9 31.9 25.5 23.2 29.8 22.3 26.5 26.7(a) Verify that for the preceding data ¯x = 36.0 and s = 10.2 approximately.(b) Let us say that the preceding data are representative of the entire sector of (successful) financial services corporations. Find a 75% confidence interval for µ, the average annual profit per employee for all successful banks.(c) Let us say that you are the manager of a local bank with a large number of employees. Suppose the annual profits per employee are less than 30 thousand dollars per employee. Do you think that this might be somewhat low compared with other successful financial institutions? Explain by referring to the confidence interval you computed in (b).(d) Suppose the annual profits are more than 40 thousand dollars per employee. As manager of the bank, would you feel somewhat better? Explain by referring to the confidence interval you computed in (b).(e) Repeat (b), (c), and (d) for a 90% confidence level.
