The paper “Effects of a Rice-rich versus Potato-rich Diet on Glucose, Lipoprotein, and Cholesterol Metabolism in Noninsulin-Dependent Diabetics” (American Journal of Clinical Nutrition [1984]: 598–606) gave the data below on cholesterol synthesis rate for eight diabetic subjects. Subjects were fed a standardized diet with potato or rice as the major carbohydrate source. Participants received both diets for specified periods of time, with cholesterol synthesis rate (mmol/day) measured at the end of each dietary period. The analysis presented in this paper used the signed-rank test. Use a test with significance level .05 to determine whether the mean cholesterol synthesis rate differs significantly for the two sources of carbohydrates.
