A recent study found that 51 children who watched a commercialfor Walker Crisps featuring a long-standing sports celebrityendorser ate a mean of 36 grams of Walker Crisps as compared toamean of 25 grams of Walker Crisps for 41 Children who watched acommercial for alternative food snack. Suppose that the samplestandard deviation for the children who watched the sportscelebrity-endorsed Walker Crisps commercial was 21.4 grams and thesample standard deviation for the children who watched thealternative food snack commercial was 12.8 grams. Assuming thepopulation variances are NOT equal and alpha=.05, is there anyevidence that the mean amount of Walker Crisps eaten wassignificantly higher for the children who watched the sportscelebrity endorsed Walker Crisps commercial?
