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
78	78
87	82
80	80
80	81
81	83
85	85
86	85
76	80
