Partial output from Microsoft Excel follows:
-Referring to Scenario 18-6,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.
