1 During one semester of a healthy living class taught at Hope College, 60 students measured body fat (as a percentage of overall weight). Body Fat was measured at the beginning of the semester and again at the end of the semester. This class is required by all undergraduates' students so we will consider this a representative sample of all college students. One of the goals of the class was to help students become healthier, including decreasing overall body fat as a percentage of weight. The data set can be found on Google CR Body-Fat (60 students) a. State the hypotheses in words and symbols. [Assume difference is calculated by Pre Class - Post Class) Ho: b. Complete the table below by entering the data set into an appropriate applet Mean SD Pre - Class Body Fat Post - Class Body Fat Mean Difference In BF c. Identify the statistic of Interest for this study, Include an appropriate symbol and interpret the meaning of this value. d. Conduct a simulation analysis. Report the p-value and attach a screenshot of your applet page - values e. Would it be valid to use a theory-based approach to determine significance? Explain. L. Regardless of your answer to (e), conduct a theory-based t-test and report the t-statistic. I - statistic : g. Using a theory-based applet, calculate the 95% confidence Interval. Interpret what this interval means. h. Based on all of the above information, do you feel this class is successful in decreasing body fat of students who take the class? Explain
