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.
