Check my work Total cost for patient = Constant, plus ax Length of stay (measured in days), plus bx Presence of one or more complications (= 1 if true, 0 if false), plus cx Use of a laparoscope (= 1 if true, 0 if false) where a, b, c are coefficients of the regression model. The laparoscope 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 63 patients, showed the following regression results: R-squared: 56% Constant term: $3,158 Coefficients and t-values for independent variables: Coefficient t-value Length of Stay $887 7.51 Complications $1,912 5.30 Laparoscope $928 2.26 Required: 1. What is the estimated cost for a patient whose surgery has complications and who stays in the hospital 4 days, and whose surgery requires a laparoscope? Dro 3F
