Question

A market research firm used a sample of individuals to rate the purchase potential of a particular product before and after the individuals saw a new television commercial about the product. The purchase potential ratings were based on a 0 to 10 scale, with higher values indicating a higher purchase potential (meaning people were more likely to buy the product after seeing the commercial). The null hypothesis stated that the mean rating “after” seeing the commercial would be less than or equal to the mean rating “before” seeing it. Rejection of this hypothesis would show that the commercial improved the mean purchase potential rating. Use a= 0.05 and the following data to test the hypothesis and comment on the value of the commercial.

A national study conducted by a market research firm, evaluated
the top technology companies and their reputations. The following
shows how 10 technology companies ranked in reputation and how the
companies ranked in percentage of respondents who said they would
purchase the company's stock. A positive rank correlation is
