Am looking for some help with these two questions

Question 1: (Part D for the test statistic is there twice but only needed once)

Drop down options for (e), 1st one: (Fail to reject, reject), 2nd: (is/is not), 3rd: (reject/support), 4th: (decreased/ changed/increasedot changed

Participants viewed two ads, one of which was the ad being tested (cola B). Participants then answered a series of questions about how much they liked the ads. An adindex measure was created and shown in the accompanying table; the higher the adindex value, the more Iikeable the ad. State your ndings and conclusions. Assume a = 0.05. a Click the icon to view the data table of the adindex ratings. Compute the descriptive statistics. Find the mean of the adindex ratings for cola A. (Round to two decimal places as needed.) Find the mean of the adindex ratings for cola B. Mean after workshops = (Round to two decimal places as needed.) Find the mean of the difference of the adindex ratings for cola Aand cola B. (Assume the difference to be the cola Adata value minus the cola B data value) Mean of the difference = (Round to two decimal places as needed.) Perform a paired ttest. Let M be the population mean adindex rating for cola Aand let p2 be the population mean adindex rating for cola B. What are the null and alternative hypotheses? O A. Ho: (10 20 (where up =p1-pz) O B. Ho: \"D so (where no =u1-p2) H1:pD0 O C. Ho: [JD =0 (where \"D =p1-p2) O D. H0: \"D #0 (where "D =p1-u2) H1zpDa0 H12uD=O Determine the test statistic. Test Statistic= (Round to two decimal places as needed.) Find the pvalue for the test statistic. The p-value is . (Round to three decimal places as needed.) State your conclusion. Ho. There sufficient evidence to conclude that the mean adindex ratings are higher for cola B than for cola A.The pass completion percentages of 10 college football quarterbacks for their freshman and sophomore seasons are shown in the table below At u= 0001, is there enough evidence to support the claim that the pass completion percentages have changed?

The pass completion percentages have changed. Let Pd be the hypothesized mean of the differences in the pass completion percentages (freshman - sophomore).
