Americans eat about 1.85 billion pounds of potato chips, or about 6.6 pounds per person annually. A study was performed with the group of 32 high school children on the annual potato chip consumption. The mean annual chip consumption among these children was found to be 8.8 pounds with standard deviation 3.5 pounds. a) If the distribution is assumed to be normal, then test the hypothesis that the group of 32 children have annual potato chip consumption different from that in the general population. b) Compute a 95% CI for the true mean annual potato chip consumption in this group. c) What is the p-value for the test?

Americans eat about 1.85 billion pounds of potato chips, or about 6.6 pounds per person annually. A study was performed with the group of 32 high school children on the

annual potato chip consumption. The mean annual chip consumption among these children was found

to be 8.8 pounds with standard deviation 3.5 pounds.

a) If the distribution is assumed to be normal, then test the hypothesis that the group of 32 children

have annual potato chip consumption different from that in the general population.

b) Compute a 95% CI for the true mean annual potato chip consumption in this group.
