Question

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 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 the parts below. Use a 0.05 significance level Test the claim that the contents of cans ol Giet seda have weights with a mean that is less than the mean for the regular soda. What are the null and alternative hypotheses? O A. Ho H.72 H, H2 OB. H 11-12 HH2 D. Ho H1 =12 HP12 0 C. Hg |-| The test statistic. tis 469(Round to two decimal places as needed.) State the conclusion for the test O A. Reject the nul hypothesis. There is sufficient evidence to support the claim that the cans of diet soda have mean weights that are lower than the mean wight for the regular sada. O B. Fail to reject the null hypothesis. There is not 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, OC. Reject the null hypothesis. There is not sufficient evidence to support the claim that the cans of det soda have mean weights that are lower than the mean weight for the regular soda. OD. Fail to read 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.
