question 328

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: Y = Weight-loss (in pounds) = Length of time in weight-loss program (in months) = 1 if morning session, 0 if not = 1 if afternoon session, 0 if not (Base level = evening session) 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:
-Referring to Scenario 18-6, which of the following statements is supported by the analysis shown?

• A)There is sufficient evidence (at = 0.05)of curvature in the relationship between weight-loss (
• Y)and months in program( ).
• B)There is sufficient evidence (at = 0.05)to indicate that the relationship between weight-loss (
• Y)and months in program ( )depends on session time.
• C)There is sufficient evidence (at = 0.10)to indicate that the session time (morning, afternoon, evening)affects weight-loss (
• Y).
• D)There is insufficient evidence (at = 0.10)to indicate that the relationship between weight-loss (
• Y)and months in program( depends on session time.
