Q2: Dataset VegetarianDiet.xls are a sample of cholesterol levels taken from 24 hospital employees who were on a standard American diet and who agreed to adopt a vegetarian diet for 1 month. Serum-cholesterol measurements were made before adopting the diet and 1 month after. 2.1. Compute the mean change in cholesterol. 2.2. Compute the standard deviation of the change in cholesterol. 2.3. Compute the median change in cholesterol 2.4. Generate a box plot of the cholesterol change 2.5. Some investigators believe that the effects of diet on cholesterol are more evident in people with high rather than low cholesterol levels. If you split the data in Table 2.15 according to whether baseline cholesterol is above or below the median, can you comment descriptively on this (calculate the descriptive statistics and show as boxplots for the two distributions).
