Chapter 12, Problem 9E

(choose chapter or problem)

The data from a patient satisfaction survey in a hospital are in Table E12-1.

The regressor variables are the patient’s age, an illness sever-ity index (higher values indicate greater severity), an indicator variable denoting whether the patient is a medical patient (0) or a surgical patient (1), and an anxiety index (higher values indicate greater anxiety).

Fit a multiple linear regression model to the satisfaction response using age, illness severity, and the anxiety index as the regressors. Estimate \(\sigma^{2}\)Find the standard errors of the regression coefficients. Are all of the model parameters estimated with nearly the same precision?  Why or why not?
