Suppose that a health researcher is interested in determining whether the distance between the patient's residence and source of care, and # of disability days significantly predict the number of visits at a local hospital.

1. Determine the multiple regression equation for the data and interpret the regression coefficients.
2. Provide an interpretation of the coefficient of multiple determination, R2.
3. At the 5% significance level, determine if # of disability days and distance between patient's residence and source of care significantly predict the number of visits.
