Physiological measurements Body Temperature: This is the body ability of the body to generate and get rid of heat. It is measured via the mouth‚ ear‚ forehead and armpit. The hypothalamus in the brain regulates body temperature. Body temperature is maintained by constant burning of fuel in cells. It burns carbohydrates and fat.

9.18 a) Using forward stepwise regression to find the best subset of predictor variables to predict job proficiency. The Alpha-to-Enter significance level was set at 0.05 and the Alpha-to-Leave significance level was set at 0.10. The first predictor entered into the stepwise model is X3. SAS tells us that the estimated intercept is -106.13 and the estimated slope for X3 is 1.968. The R2-value is 0.8047‚ mean square error is 76.87. The second predictor entered into the stepwise model is X1.
