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 13 pounds. Use the =α0.05 level of significance and the P-value method with the TI-84 Plus calculator.21.227.56.522.82011.516.219.736.332.511.134.822.417.9Send data to ExcelPart: 0 / 50 of 5 Parts Complete Part 1 of 5 (a) State the appropriate null and alternate hypotheses.
