TABLE 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: Data for 12 clients on a weight-loss program at the clinic were collected and used to fit the interaction model: Partial output from Microsoft Excel follows: Regression Statistics ANOVA -Referring to Table 14-11, which of the following statements is supported by the analysis shown? A) There is sufficient evidence (at α = 0.05) of curvature in the relationship between weight-loss ( Y) and months in program(X₁). B) There is sufficient evidence (at α = 0.05) to indicate that the relationship between weight-loss ( Y) and months in program (X₁) depends on session time. C) There is sufficient evidence (at α = 0.10) to indicate that the session time (morning, afternoon, evening) affects weight-loss ( Y). D) There is insufficient evidence (at α = 0.10) to indicate that the relationship between weight-loss ( Y) and months in program (X₁) depends on session time.
