To assess the effectiveness of a cola video ad for cola B a random sample of 35 individuals from a target audience was selected to participate in a copy test. 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 likeable the ad State your findings and conclusions Assume a = 0.05. Click the icon to view the data table of the adindex ratings. Mean after workshops = (Round to two decimal places as needed ) Find the mean of the difference of the adindex ratings for cola A and cola B. (Assume the difference to be the cola A data value minus the cola B data value) Mean of the difference = (Round to two decimal places as needed.) Perform a paired ! test. Let py be the population mean adindex rating for cola A and let pg be the population mean adindex rating for cola B. What are the null and alternative hypotheses? OA. Ha UD =0 (where 10 = 14 -12) B. Ha Up $0 (where po = 141 -12) H, HD -0 O C. Ha Up #0 (where po = 14 - 12) OD, Ha Up 20 (where po " #1 - 12) Determine the test statistic Test Statistic = (Round to two decimal places as needed.] Find the p-value for the test statistic The p-value is (Round to three decimal places as needed ] State your conclusion Hy. There sufficient evidence to conclude that the mean adindex ratings are higher for cola B than for cols A
