Question

A recent study found that 62 children who watched a commercial for potato chips featuring a celebrity endorser ate a mean of 39 grams of potato chips as compared to a mean of 25 grams for 52 children who watched a commercial for an alternative food snack. Suppose that the sample standard deviation for the children who watched the celebrity-endorsed commercial was 21.4 grams and the sample standard deviation for the children who watched the alternative food snack commercial was 12.9 grams.

Assuming that the population variances are equal, construct a

95% confidence interval estimate of the difference μ1−μ2 between the mean amount of potato chips eaten by the children who watched thecelebrity-endorsed commercial and children who watched the alternative food snack commercial.

Based on the results of (a) and (b) if you wanted to increase the consumption of this brand of potato chips, which commercial would you choose?

A. Choose the commercial with the celebrity endorser since there is evidence that the mean amount of potato chips eaten was significantly lower for children who watched the celebrity-endorsed commercial.

B. Choose the commercial without the celebrity endorser since there is evidence that the mean amount of potato chips eaten was significantly lower for children who watched the celebrity-endorsed commercial.

C. Choose the commercial with the celebrity endorser since there is evidence that the mean amount of potato chips eaten was significantly higher for children who watched the celebrity-endorsed commercial.

D. Choose the commercial without the celebrity endorser since there is evidence that the mean amount of potato chips eaten was significantly higher for children who watched the celebrity-endorsed commercial.
