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 **length of stay (measured in days), plus bPresence of one or more complications if true, it false) plus CUse of a laparoscope it true o Mfalse) where care 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 6t patients, showed the following regression results squared: 55 Constant term $3247 Coefficients and Values for independent variables con of a $100 11 5140 Tamariscope 27 Required: 1.
