I need the answer for part 2 the correlation

Foot temperatures: Foot ulcers are a common problem for people with diabetes. Higher skin temperatures on the foot indical an increased risk of ulcers. In a study performed at the Colorado School of Mines, skin temperatures on both feet were measur in degrees Fahrenheit, for 8 diabetic patients. The results are presented in the following table. Use a TI-84 Plus calculator to answer the following. Left Foot Right Foot 89 86 88 89 89 90 88 86 89 87 87 82 78 78 86 85 @ Send data to Excel (a) Construct a scatterplot of the right foot temperature (y) versus the left foot temperature (x). 92 - 90 38 + 86 - Right Foot Temperature (F) 84 82- 80 - 78 76 74 - 72 + 70 72 74 76 78 80 82 84 86 88 90 92 Left Foot Temperature (F)Part 2 of 4 three decimal places. (b) Compute the correlation coefficient between the temperatures of the left and right feet. Round the answer to at least The correlation coefficient is r = X 5
