Question: In a study conducted in Italy .10 patients with hypertriglyceridemia were placed on a low-fat, high-carbohydrate diet. Before the start of diet, cholesterol and triglyceride measurements were recorded for each subject.

Patient Cholesterol Level (mmol/1) Triglyceride Level (mmol/1)

1 5.12 2.3

2 6.18 2.5

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

Construct a scatter plot for these data.

Does there appear to be any evidence of a linear relationship between cholesterol and triglyceride levels prior to the diet?

Compute the correlation coefficient.
