Foot temperatures: Foot ulcers are a common problem for people with diabetes. Higher skin temperatures on the foot indicate an increased risk of ulcers. In a study performed at the Colorado School of Mines, skin temperatures on both feet were measured, in degrees Fahrenheit, for 8 diabetic patients. The results are presented in the following table. Use a TI-84 calculator to answer the following. Left Foot 85 88 78 89 87 80 88 89 Right Foot 85 86 78 87 82 80 89 90 Compute the least-squares regression line for predicting the right foot temperature from the left foot temperature. Round the slope and y-intercept values to four decimal places. Draw a scatterplot of the right foot temperature (V) versus the left foot temperature (X). Then draw the least-squares regression line on the graph. Foot temperatures: Foot ulcers are a common problem for people with diabetes.
