Question 8

In a study to determine whether counseling could help people lose 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, 14.7

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.

Write down your P-value. You will need it for the next question.

Write only a number as your answer. Round to four decimal places (for example: 0.3841).
