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 foiom'ng table. Use a 1184 calculator to answer the folowing. Left Foot Right Foot 78 T8 89 90 80 80 76 81 89 86 85 85 87 82 80 81 Compute the leastsquares regression ne for predicljng the right foot temperature from the left foot temperature. Round the slope and y-intercept values to four dedmal places. A y = 0.61963: + 31.4511 Part 3 of 4 V If the left foot temperatures of two patients differ by 5 degrees, by how much would you predict their right foot temperatures to differ? Round the answer to three decimal places. The right foot temperatures would differ by 3.098 degrees. Part: 3 / 4 Part 4 of 4 Predict the right foot temperature for a patient whose left foot temperature is 83 degrees. Round the answer to one decimal place. The right foot temperature is predicted to be 3.1 degrees. X
