Question 1
Which of the following is not a possible indicator of multicollinearity?
◦ non-significant
t-tests for individual
β parameters when the
F-test for overall model adequacy is significant
◦ non-random patterns in the plot of the residuals versus the fitted values
◦ signs opposite from what is expected in the estimated β parameters
◦ significant correlations between pairs of independent variables
Question 2
The printout below shows part of the least squares regression analysis for the model

fit to a set of data. The model attempts to predict a score on the final exam in a statistics course based on the scores on the first two tests in the class.

Is there evidence of multicollinearity in the printout? Explain.
