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.
