To assess the effectiveness of a cola video ad, a random sample of 38 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. Participants then answered a series of questions about how much they liked the ads. An adindex measure was created and stored in Adindex ; the higher the adindex value, the more likeable the ad. Compute descriptive statistics and perform a paired t test. State your findings and conclusions in a report. (use the 0.05 level of significance.)
