SCENARIO 14-11 A weight-loss clinic wants to use regression analysis to build a model for weight loss of a client (measured in pounds).Two variables thought to affect weight loss are client's length of time on the weight-loss program and time of session.These variables are described below: Y Weight loss (in pounds) Length of time in weight-loss program (in months) 1 if morning session, 0 if not Data for 25 clients on a weight-loss program at the clinic were collected and used to fit the interaction model: Y Output from Microsoft Excel follows:
-Referring to Scenario 14-11, the overall model for predicting weight loss (Y)is statistically significant at the 0.05 level.

The output shows that the p-value for the overall model is less than 0.05, indicating that the model is statistically significant at the 0.05 level. The output table shows that the p-value for the F-statistic is less than 0.05, indicating that the overall model is statistically significant.
