This problem was modified from m. This study used a cross-over trial experiment to investigate whether eating oat bran lowered serum cholesterol levels. Twelve individuals were randomly assigned a diet that included either oat bran or corn akes. After two weeks on the initial diet, serum cholesterol (mmol/L) was measured and then participants were \"crossed-over\" to the other diet. After two-weeks on the second diet, cholesterol levels were measured again. Calculate the 98% confidence interval for the population difference in mean serum cholesterol for people eating oat bran and those eating cornakes \"by-hand\" by coding the steps in R. Then use an R function to check your results. Report and interpret the interval in the context of the problem. (3 points)
