TABLE 14-11 A Weight-Loss Clinic Wants to Use Regression Analysis to Build

question 76

True/False

TABLE 14-11
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)
X₁ = Length of time in weight-loss program (in months)
X₂ = 1 if morning session,0 if not
Data for 25 clients on a weight-loss program at the clinic were collected and used to fit the interaction model:
Y = β₀ + β₁X₁ + β₂X₂ + β₃X₁X₂ + ε
Output from Microsoft Excel follows:
-True or False: Referring to Table 14-11,the overall model for predicting weight loss (Y)is statistically significant at the 0.05 level.
