Question: Problem 16 in Chapter 11 described a study examining the effect of eating oatmeal regularly on cholesterol. Cholesterol was measured before and after adding oatmeal to the diet of a sample of n = 9 participants. For this sample, cholesterol scores averaged MD = 16 points lower with the oatmeal diet with SS = 538 for the difference scores. Use the data to estimate how much effect oatmeal would have on the cholesterol level for the general population. Make a point estimate and a 95% confidence interval estimate of the population mean difference.
