An SRS of nine adults went on a low-fat diet for 10 weeks to lower cholesterol. Here are the data for these subjects (labeled A-I). I've included some means and standard deviations, but you won't need all of this information.

You will do parts of a hypothesis test to find out. We take the population to be all adults. Let u be the population mean difference in cholesterol (starting -ending). (a) Write the hypotheses for this test. (b) Assuming the criteria to do a hypothesis test have already been checked, give the appropriate test statistic. 20 B.
