1 3 points eBook Print References 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 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, O 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 60 patients, showed the following regression results: R-squared: 52% Constant term: $3,630 Coefficients and t-values for independent variables: Coefficient t-value Length of Stay $ 734 8.45 Complications Laparoscope $1,602 5.01 $ 948 2.47 Required: 1. What is the estimated cost for a patient whose surgery has complications and who stays in the hospital 5 days, and whose surgery requires a laparoscope? Estimated cost Check my work
