In a study to determine whether counseling could help people loose weight, a sample of people experienced a group-based behavioral intervention, which involved weekly meetings with a trained interventionist for a period of six months. The following data are the numbers of pounds lost for 5 people.
18.2, 3.9, 17.1, 8.8, 19.6
It is reasonable to assume that the population is approximately normal. A researcher wants to know whether the mean weight loss is greater than 10 pounds. Compute the P-Value of the test.
