CoursHeroTranscribedText: Recent research into the cost of various medical procedures has shown the impact of certain complications encountered in surgery on the total cost ofa 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 iftrue, 0 if false), plus c X Use of a laparoscope (=1 if true, 0 if false) where a, b, care coefficients of the regression model. The laparoscope is an instrument somewhat like a miniature telescope with a fiberoptic 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: Rsquared: 56% Constant term: $3,158 Coefficients and tvalues for independent variables: Length of Stay Complications Laparoscope Coefficient $ 887 $ 1,912 $ 928 tvalue 7.51 5.30 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? 9 Answer is complete but not entirely correct. $ 9,4566
