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 Right Foot 85 85 88 86 78 78 89 87 87 82 80 80 88 89 89 90 Send data to Excel Part: 0 / 4 Part 1 of 4 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. y = 8.2857 + 0.8929x X 5 Part: 1 / 4 Part 2 of 4 Draw a scatterplot of the right foot temperature ()) versus the left foot temperature (X). Then draw the least-squares regression line on the graph
