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 = 0.05. 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 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 t test. Let be the population mean adindex rating for cola A and let be the population mean adindex rating for cola B. What are the null and alternative hypotheses? OA. Ho HD 50 (where D = 1-2) H: HD >0 OC. Ho: HD #0 (where HD =1-2) OB. Ho HD 20 (where HD - H1-H2) H: HD <0 OD. Ho HD = 0 (where D = 1-H2) 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. Ho. There sufficient evidence to conclude that the mean adindex ratings are higher for cola B than for cola A.
