A Study of the Top MBA Programs Attempted to Predict $75 \quad$

question 122

Multiple Choice

A study of the top MBA programs attempted to predict the average starting salary (in $1000ʹs) of graduates of the program based on the amount of tuition (in $1000ʹs) charged by the program and
The average GMAT score of the programʹs students. The results of a regression analysis based on a
Sample of 75 MBA programs is shown below: Least Squares Linear Regression of Salary

The global- $\mathrm { f }$ test statistic is shown on the printout to be the value $\mathrm { F } = 84.68$ . Interpret this value.

• A) There is insufficient evidence, at \(\alpha = 0.05\), to indicate that the interaction between average tuition and average GMAT score is a useful predictor of the average starting salary of graduates of MBA programs.
• B) There is sufficient evidence, at \(\alpha = 0.05\), to indicate that the interaction between average tuition and average GMAT score is a useful predictor of the average starting salary of graduates of MBA programs.
• C) There is insufficient evidence, at \(\alpha = 0.05\), to indicate that at least one of the variables proposed in the interaction model is useful at predicting the average starting salary of graduates of MBA programs.
• D) There is sufficient evidence, at \(\alpha = 0.05\), to indicate that at least one of the variables proposed in the interaction model is useful at predicting the average starting salary of graduates of MBA programs.
