Weight loss: In a study to determine whether counseling could help people lose weight, a sample of people experlenced a group-based behavioral intervention, which involved weekly meetings with a trained interventionist for a perlod of six months. The following data are the numbers of pounds lost for 14 people. Assume the population is approximately normal.

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 a=0.05 level of significance and the P-value method with the TI-84 Plus calculator.

College tuition: The mean annual tuition and fees in the 2013-2014 academic year for a sample of 13 private colleges in California was $38,000 with a standard deviation of $7900. A dotplot shows that it is reasonable to assume that the population is approximately normal. Can you conclude that the mean tuition and fees for private institutions in California differs from $35,0007 Use the a = 0.01 level of significance and the P-value method with the TI-84 Plus calculator.
