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 thep-value?d. What is the 95% confidence interval estimate of the change in occupancy for theone-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 askedif 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 Yesand 74 of the women replied Yes, are the results statistically significant in thatcan conclude a greater proportion of men are expecting to get a raise or a promotionthis year?State the hypothesis test in terms of the population proportion of men and the populationproportion 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?youa.с.SummaryIn this chapter we discussed procedures for developing interval estimates and conduct-ing hypothesis tests involving two populations. First, we showed how to make inferencesabout the difference between two population means when independent random samplesare selected. We first considered the case where the population standard deviations o, and

A hypothesis test can be conducted to compare the population proportion of two independent…
