SCENARIO 14-11 a Weight-Loss Clinic Wants to Use Regression Analysis

Multiple Choice

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, which of the following statements is supported by the analysis shown?

A) There is sufficient evidence (at = 0.05) of curvature in the relationship between weight loss (Y) and months on program
B) There is sufficient evidence (at = 0.05) to indicate that the relationship between weight loss (Y) and months on program varies with session time.
C) There is insufficient evidence (at = 0.05) of curvature in the relationship between weight loss (Y) and months on program
D) There is insufficient evidence (at = 0.05) to indicate that the relationship between weight loss (Y) and months on program varies with session time.
