help solve attached, and following parts pertaining to attached image, all parts please.
find test statisitic t
find p value
State the conclusion for the test.
A. 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.
Your answer is not correct.b. Construct a confidence interval appropriate for the hypothesis test in part (a).
_____ lb<μ1−μ2< ____lb
final part*
Does the confidence interval support the conclusion found with the hypothesis test?
Yes or no, because the confidence interval contains zero or only negative values or only positive values.
![A study was done on proctored and nonproctored tests. The results are shown in the table. 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.

a. Use a 0.01 significance level to test the claim that students taking nonproctored tests get a higher mean score than those taking proctored tests.
What are the null and alternative hypotheses?
A. Ho: H1 =

O C. Ho: H1 # H2
H1: H1 <H2
