SCENARIO 18-6 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: 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.

The p-value for the interaction term (XS1U1B2S1U1B0) is 0.109, which is greater than 0.10. Therefore, there is insufficient evidence (at α = 0.10) to indicate that the relationship between weight-loss (Y) and months in the program (XS1U1B11S1U1B0) depends on session time.
