The Adecco Workplace Insights Survey sampled men and women workers and asked if they expected to get a raise or promotion this year (USA Today, February 16, 2012). Suppose the survey sampled 200 men and 200 women. If 104 of the men replied Yes and 74 of the women replied Yes, are the results statistically significant in that you can conclude a greater proportion of men are expecting to get a raise or a promotion this year? State the hypothesis test in terms of the population proportion of men and the population proportion of women? b. What is the sample proportion for men? For women? Use a .01 level of significance. What is the p-value and what is your conclusion? a. с.

Answer the Adecco Workplace Insights Survey problem

b. What is the estimated proportion of hotel rooms occupied each year? c. Using a .05 level of significance, what is your hypothesis test conclusion? What is the p-value? d. What is the 95% confidence interval estimate of the change in occupancy for the one-year period? Do you think area officials would be pleased with the results? 7. The Adecco Workplace Insights Survey sampled men and women workers and asked if they expected to get a raise or promotion this year (USA Today, February 16, 2012). Suppose the survey sampled 200 men and 200 women.

What is the p-value and what is your conclusion? you a. с. Summary In this chapter we discussed procedures for developing interval estimates and conduct- ing hypothesis tests involving two populations. First, we showed how to make inferences about the difference between two population means when independent random samples are selected. We first considered the case where the population standard deviations o, and
