() Suppose you conducted a sample of hotel rates in DC and GA.

DC: sample mean - $126.15, sample size - 35, standard deviation - $42

GA: sample mean - $135.60, sample size - 46, standard deviation - $39

test the hypothesis that the average hotel rate in DC is not equal to the average room rate in GA by comparing the calculated z-score to the critical z-score with level of significance of 0.05.

() Suppose you want to test a claim that the average age of men and women at a retirement center "are not equal." Here is the samples:

men: sample mean - 84.5, sample size - 17, standard deviation - 6.0

women: sample mean - 87.1, sample size - 14, standard deviation - 7.3

Test the claim at the 0.02 significance level.

() Suppose you sample the salary of two car sales man from two different states, New Yersey and Delaware. Test the hypothesis that the average salesman in NJ is more than the average in Delaware by comparing the calculated z-score to the critical z-score at a 0.05 significance level.

NJ: sample mean - $52,378, sample size - 40, standard deviation - $6,812

DL: sample mean - $48,773, sample size - 42, standard deviation - $7,514
