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 17 pounds. Use the α=0.05 level of significance and the P-value method with the TI-84 Plus calculator. 22.3 28.2 7.3 23.7 21.2 12.6 17.1 20.8 37.3 33.5 11.8 36.1 23.7 19.2
