A television documentary on overeating claimed that Americans are about 10 pounds overweight on average (μ). To test this claim, 18 randomly selected individuals were examined; their average (x̄) excess weight was found to be 12.4 pounds, and the sample standard deviation (s) was 2.7 pounds. At a significance level of 0.01, is there any reason to doubt the validity of the claimed 10-pound value?
Homework Answers
