Document Summary

Multiple linear regression / model building mba exercise. The following three predictors were suggested: 18. 6 the dean believes that an interaction affect may exist between undergraduate gpa and the gmat scores. The output is as follows. The sample regression line (prediction line) is. Mba gpa= - 11. 11 + 1. 19undergpa + 0. 0311gmat + 0. 0956work - 0. 0019undergpa gmat. S= . 790 (compare it to y- bar if available) We say 46. 74% of the variation in y is explained by the regression model, and 1- 46. 74 % . H0 = 1 = 2 = 3 = 4 = 0. H1 = at least one of the coefficients i is not zero. We can also see this from the p- value = 0. The model is valid, but the fit is relatively poor due to low r- square. Question is asking for whether there is interaction among two variables or not.
