Data on the weights (Ib) of the contents of cans of diet soda versus the contents of cans of the regular version of the soda is summarized to the right. Assume that the two Regular Diet samples are independent simple random samples selected from normally distributed populations, and do not assume that the population standard deviations are equal. Complete parts (a) and (b) below.. Use a 0.01 significance level for both parts. 27 0.79037 Ib 0.00449 Ib 27 0,80399 Ib 0.00756 Ib a. Test the claim that the contents of cans of diet soda have weights with a mean that is less than the mean for the regular soda. What are the null and alternative hypotheses? OA Ho: H1" 2 B. Ho: HH2 OC. Ho: H1 "42 H: H > H2 MD. Ho HP2 The test statistic, t, is (Round to two decimal places as needed.)

You developed a way to measure anger people.  Test the claim that the mean score of anger for younger people is equal to the mean score for older people. Use a significance level of .06.  The scores are listed below. Scores for younger people: 25, 33, 19, 8, 39, 29, 28, 18, 41, 3, 27, 35, 14, 25, 36, 4, 11 Scores for older people: 38, 35, 21, 5, 19, 22, 35, 33, 54, 3, 55, 9, 15, 22, 47, 4, 21
