26. The nutrition label on a bag of potato chips says that a one
ounce (28 gram) serving of potato chips has 126 calories and
contains ten grams of fat, with three grams of saturated fat. A
random sample of 32 bags yielded a sample mean of 130 calories with
a standard deviation of 16 calories. Is there evidence that the
nutrition label does not provide an accurate measure of calories in
the bags of potato chips? We have verified that the independence,
sample size, and skew conditions are satisfied. Set this up as a
hypothesis test using α=0.01, and show your work for full
credit.
