Data on the weights (lb) of the contents of cans of diet soda versus the contents of cans of the regular version of the soda Diet Regular is summarized to the right. Assume that the two 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 0.05 significance level for both parts. 0.78131 lb 0.81807 lb 0.00436 lb 0.00745 lb WB. Ho: H1 = H2 OA HO: H1 = H2 H,: Hy - H2 H,: 1 1 H2 O D. Ho: P1 - H2 OC.
