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. __ ≤μ1−μ2≤ __ (Type integers or decimals rounded to two decimal places as needed.) The mean amount of chips eaten by children that watch the commercial featuring the celebrity is between 3.34 and 16.66 grams more than the children that don't. since the interval is > 0, the decision to reject Ho is valid... 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.
