| 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 parts (a) and (b) below.
Use a 0.01 significance level for both parts. |

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?
The test statistic, t, is?
(Round to two decimal places as needed.)
The P-value is ?
(Round to three decimal places as needed.)
State the conclusion for the test.
A. Reject he 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. 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.
C. 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.
D. 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.
b. Construct a confidence interval appropriate for the hypothesis test in part (a).
? lbs <u 1 - u2 < lb?
(Round to three decimal places as needed.)
Does the confidence interval support the conclusion found with the hypothesis test? because the confidence interval contains ?

Question 4 (1.25 points) Soda cans of a certain kind are labeled as containing 12 ounces. A quality control inspector believes that the mean weight may be more than this, so she performs a hypothesis test of Ho: mean = 12 versus Hy: mean > 12. She does not reject the null hypothesis. Which of the following is an appropriate conclusion? " There is not enough evidence to conclude that the mean weight of the soda in the cans is...
