To assess the electiveness of a cola video ad for a B, a randon mple 61 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. Ar 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 α = 0.05. Find the variance of the cola A adindex ratings. (Round to two decimal places as needed.) Find the variance of the cola B adindex ratings. (Round to two decimal places as needed.) Find the variance of the difference of the adindex ratings for cola A and cola B. (Round to two decimal places as needed.) Perform a paired t test. Let μ, be the population mean adindex rating for cola A and let μ₂ be the population mean adindex rating for cola B. What are the null and
