(Click the icon to view the past year data.) (Click the icon to view discussion results.) Read the requirements. Begin by running a multiple regression to estimate the regression equation for medical supplies costs using both number of procedures and number of patient-hours as independent variables. You should obtain the following result: Regression 3: Medical supplies costs = a (b * No. of procedures) + (b * No. of patient-hours) Variable Constant Independent variable 1: No. of procedures Independent variable 2: No. of patient-hours =0.84; Durbin-Watson statistic = 1.96 Coefficient Standard Error t-Value $ -3,103.76 $ 30,406.54 -0.10 p-value 0.921 $ 38.24 $ $ 54.37 $ 100.76 10.33 5.26 0.38 0.713 0.001 Requirement 1. Evaluate the multiple regression output using the criteria of economic plausibility, goodness of fit, significance of independent variables, and specification of estimation assumptions.
