question 116

Multiple Choice

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.
