Foot ulcers are a 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 181 diabetic patients. The results are presented in the following table. Left Foot Right Foot 80 80 85 85 75 80 88 86 89 87 87 82 78 78 88 89 89 90 76 81 89 86 87 82 78 78 80 81 87 82 86 85 76 80 88 89 Construct a scatterplot of the right foot temperature (y) versus the left foot temperature (x). Verify that a linear model is appropriate. b. Compute the least-squares line for predicting the right foot temperature from the left foot temperature. If the left foot temperatures of two patients differ by 2 degrees, by how much would you predict their right foot temperatures to differ? Predict the right foot temperature for a patient whose left…
In Table 4, the dependent variable is academic self-efficacy and the independent variables are 1) symptoms of anxiety and depression, 2) social loneliness, 3) financial vulnerability, and 4) hours spent on studies per week. Look at the model 2, find OR that is statistically significant. What does OR=4.01 mean in the model 2 above? Fill out the blanks and choose the right word in the parenthesis below. Low academic self-efficacy Few or moderate anxiety Odds ratio=1 (reference) Severe anxiety Odds ratio=4.01 (95% CI=2.40, 6.69) Students with severe anxiety are ( ) times ( ) likely to have low academic self-efficacy and this is statistically (significant/non-significant).
