Data on the weights (Ib) of the contents of cans of diet soda versus the contents of Diet Regular cans of the regular version of the soda is summarized to the right. Assume that H1 H2 the two samples are independent simple random samples selected from normally n 33 33 distributed populations, and do not assume that the population standard deviations are equal. Complete parts (a) and (b) below. Use a 0.01 significance X 0.79615 lb 0.81301 lb level for both parts. S 0.00438 lb 0.00751 lb . . . have mean weights that are lower than the mean weight for the regular soda. O C. Fail to reject the null hypothesis. There is sufficient evidence to support the claim that the cans of diet soda have mean weights that are lower than the mean weight for the regular soda. D. Reject the null hypothesis. There is sufficient evidence to support the claim that the cans of diet soda have mean weights that are lower than the mean weight for the regular soda. b. Construct a confidence interval appropriate for the hypothesis test in part (a). 16
