With dаtа frоm n = 95 hоspitаls, a regressiоn is done to analyze the relationship between Y = InfctRsk, the infection risk at a hospital (as a percent) and X1 = Stay, the average length of patient stay (days), X2 = X-rays, the percentage of patients who get x-rays at the hospital, X3 = Nurses, the number of nurses employed at the hospital, and X4 = Facilities, a measure of how many medical services are available at the hospital. We fit a multiple regression model, Y = β0 + β1X1 + β2X2 + β3X3 + β4X4 +ε, to the data with results as follows: Analysis of Variance Source DF Adj SS Adj MS F-Value P-Value Regression 4 94.560 23.6401 24.15 0.000 Error 90 88.117 0.9791 Total 94 182.677 Coefficients Term Coef SE Coef T-Value P-Value Constant -2.136 0.757 -2.82 0.006 Stay 0.4385 0.0848 5.17 0.000 Xray 0.01844 0.00605 3.05 0.003 Nurses 0.00151 0.00118 1.28 0.204 Facilities 0.0095 0.0110 0.86 0.392 Regression Equation InfctRsk = -2.136 + 0.4385 Stay + 0.01844 Xray + 0.00151 Nurses + 0.0095 Facilities Note: Scatterplots and residual plots (not shown here) suggest no difficulties with these data or the model.
