The data shown in Table 2 are based on a study conducted with a group of dietitians to see if the number of grams of fat per daily intake is related to cholesterol levels. If there is a significant relationship, predict the cholesterol level of a person on a diet consuming 8.5 grams of fat per day. Fat grams x Cholesterol level y 6.8 Table 2 5.5 8.2 10 183 201 8.6 a. Draw the scatter plot. b. Compute the value of the correlation coefficient. c. Test the significance of the correlation coefficient at a = 0.05. 9.1 8.6 10.4 193 283 222 250 190 218 (6 marks) (6 marks) (5 marks) d. Determine the regression line equation if r is significant. (2 marks) e. Plot the regression line on the scatter plot if appropriate. (2 marks) f. Predict y' for a specific value of x if appropriate. (2 marks) g. Find the standard error of the estimate. (5 marks) h. Find the 95% prediction interval of the cholesterol level of a person who consumes 10 grams of fat. (2 marks)
