Recent research into the cost of various medical procedures has shown the impact of certain complications encountered in surgery on the total cost of a patient's stay in the hospital. The researchers used regression analysis and found the following results: Total cost for patient = Constant, plus a x Length of stay (measured in days), plus b x Presence of one or more complications (= 1 if true, 0 if false), plus c * Use of a laparoscopy (= 1 if true, 0 if false) where a, b, care coefficients of the regression model. The laparoscopy is an instrument somewhat like a miniature telescope with a fiber-optic system that brings light into the abdomen. It is about as big around as a fountain pen and twice as long. The research, based on 60 patients, showed the following regression results: R-squared: 52% Constant term: $3,630 Coefficients and t values for independent variables: implications Laparoscopy 7BE 191 45 2 2, 602 6. 01 2 . 147 not Requireda 1.
