Regression Equation:
The regression equation from the excel output is:
-1267666.157 + 178512.21*Staffed Beds_05 – 1117.15*Medicare Days_05 – 352.889*Medicaid Days_05 + 1935.23*Total Surgeries_05 + 333072.73*RN FTE_05 + 3752420.245*Occupation – 15595326.25*Ownership +7469768.966*System Membership – 6828203.672*Rural/Urban -17012822.3*Teaching Affiliation – 479.524*Age 65 plus_05 – Crime Rate + 523.368*Uninsured 2005
Predictor Variables Hypothesis:
Null Hypothesis [H0] = Total Operating Expense_05 doesn’t depend on predictor variable
Alternative Hypothesis [Ha] = Total Operating Expense_05 depends on predictor variable
The null hypothesis will be rejected when the predictor variables for the p-value from the regression output table is less than 0.05, besides total operating expense_05 will depend on that predictor value. Therefore, from the regression output table, the Total Operating Expense_05 depends on Staff Beds-05; Medicare Days-05; Total Surgeries_05; and RN FTE-05.

The Model R-Square value = 0.968
Interpretation:
The results above indicate that the total operating expenses depend positively significantly on four aspects that include Staffed Beds_05; Medicare Days_05; Total Surgeries_05; and RN FTE_05. As a consequence, with the purpose of reducing the total operating expenses, these four aspects should be taken into consideration. Furthermore, from the regression equation, it is evident that the variables have a positive sign, except Medicare Days; implying that increase in these variables, will correspondingly lead to an increase in the total operating expenses. For instance, a unit increase in total surgeries, RN FTE, and staffed beds will lead to an increase in total operating expenses by 1935.23, 333072.7317, and 178512.2197 respectively.
