A recent study found that 63 children who watched a commercial for potato chips featuring a celebrity endorser ate a mean of 40 grams of potato chips as compared to a mean of 26 grams for 53 children who watched a commercial for an altemative food snack. Suppose that the sample standard deviation for the children who watched the celebrity-endorsed commercial was 21.4grams and the sample standard deviation for the children who watched the alternative food snack commercial was 12.6 grams. Complete parts (a) through (d) below. a) Rainct H. Thare ic insufficiont ovictanne that the mean amnint nf notatn ahine aatan wae significantly higher for children who watched the celebrity-endorsed commercial. b. Assuming that the population variances are equal, construct a 95% confidence interval estimate of the difference 12 between the mean amount of potato chips eaten by the children who watched the celebrity-endorsed commercial and children who watched the alternative food snack commercial. (Type integers or decimals rounded to two decimal places as needed.)
