Brand A :11 17 29 10 28 37 29 31 19 44 Brand B: 22 16 28 12 18 36 23 11 41 29 At the 0.01% significance level, conclude the mean numbers of calories per packet are different for these two brands of junk food? Assume that the calories per packet of junk food are normally distributed for each of the two brands. 1) Is there enough evidence to conclude that the mean amount of calories in Brand A is more than the mean of amount of calories in Brand B? Use a = 0.05 2) Construct 95% confidence interval for the difference in the mean amount of calories in these two brand. Explain.
