Q1 Foot ulcers are common problem for people with diabetes. Higher skin temperatures on the foot indicate an increased risk of ulcers. The article “An Intelligent Insole for Diabetic Patients with the Loss of Protective Sensation" (Kimberly Anderson, M.S. Thesis, Colorado School of Mines), reports measurements of temperatures, in °F, of both feet for 18 diabetic patients. The results are presented in the Table Q1. Table Ql: Measurements of temperatures, in °F of left foot Vs right foot for 18 diabetic patients Left Foot Right Foot Left Foot Right Foot 80 85 75 88 89 87 80 76 81 86 82 78 81 82 85 80 89 85 80 89 87 78 80 87 86 87 82 78 78 86 76 88 89 89 90 88 (a) Compute the least-squares line for predicting the right foot temperature from the left foot temperature. (b) If the left foot temperatures of two patients differ by 2 degrees, predict by how much would their right foot temperatures will differ. (c) Predict the right foot temperature for a patient whose left foot temperature is…

Step 9 (b) Use Fisher's LSD procedure to test whether there is a significant difference between the means for treatments A and B, treatments A and C, and treatments B and C. Use α = 0.05. A hypothesis test for the population of treatment means can lead to the conclusion that not all the population means are equal, but it does not indicate which population means may differ. Fisher's least significant difference, LSD, procedure can be used to pinpoint where these differences occur. The test statistic will be calculated as the absolute value of the difference between two sample means, x₁ - x;. This test statistic will be compared to the value of LSD, the formula of which is given below. The variable t/2 is based on a t distribution with n, - k degrees of freedom with a significance level of a, MSE is the mean square error, n, is the number of observations for population i, and n, is the number of observations for population j. / MSE (171, + 121,) LSD = ta/2V A significance level of a =…
