Data on the weights (Ib) of the contents of cans of diet soda versus the contents of cans of the regular Diet Regular version of the soda is summarized to the right. Assume that the two samples are independent simple Hy H2 random samples selected from normally distributed populations, and do not assume that the population n 39 39 standard deviations are equal. Complete parts (a) and (b) below. Use a 0.05 significance level for both 0.78881 lb 0.81771 lb parts X S 0.00438 lb 0.00759 lb 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? CE O A. Ho: My = H2 OB. HO: H1 # H2 ER Hy: Hy * H2 Hy: My H2
