5. In a study conducted in Italy, 10 patients with hypertriglyceridemia were placed on a low-fat, high-carbohydrate diet. Before the start of the diet, cholesterol and triglyceride measurements were recorded for each subject. Cholesterol Level Patient (mmol/l) Triglyceride level (mmol/l) 1 5.12 2.30 2 6.18 2.54 3 6.77 2.95 4 6.65 3.77 5 6.36 4.18 6 5.90 5.31 7 5.48 5.53 8 6.02 8.83 9 10.34 9.48 10 8.51 14.20 a. Construct a two-way scatter plot for these data. b. Use STATA to calculate Pearson's Correlation Coefficient for these data. c. Test, = 0.05, whether or not the population correlation, p, equals 0. d. Use STATA to Calculate the Spearman rank correlation coefficient, rs, for these data. e. Using rs, test the null hypothesis that the population correlation, p, equals 0. 5.
