The administrator of a new paralegal program at Seagate Technical College wants to estimate the grade point average in the new program. He thought that high school GPA, the verbal score on the Scholastic Aptitude Test (SAT), and the mathematics score on the SAT would be good predictors of paralegal GPA. The data on nine students are:
(a)
Find the estimated regression line for paralegal grade point average . Interpret your results.
(b)
Conduct a global test of hypothesis from the preceding output. Does it appear that any of the regression coefficients are not equal to zero?
(c)
Interpret the multicollinearity, and autocorrelation and heteroscedasticity of residuals.
