(c) Compute the P-value. Round the answer to at least four decimal places. (d) Determine whether to reject Ho. (e) State a conclusion.

Weight loss: 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 14 people. Assume the population is approximately normal. Perform a hypothesis test to determine whether the mean weight loss is greater than 12 pounds. Use the a= 0.01 level of significance and the P-value method with the TI-84 Plus calculator. 18.6 25.22 41 204 173 9.0 13.7 17.6 34.0 29.9 8.7 31.7 19.8 15.5
