A university wants to determine if there is any relationship between their world language secondary education students' total GPA, education class GPA, and world language GPA.

What is the coefficient of determination (1)? How much variance is shared between the predictors and score on the praxis exam? 2) Is the regression model significant? Provide a statement of results. 3) For every point increase in world language GPA, how many points is the praxis score expected to increase? For every point increase in total GPA, how many points is the praxis score expected to increase?
