Hints: Depending on context, you could argue which is the dependent variable and which is the independent variable. I chose to investigate whether obesity rates could predict total hospital expenditures. I did not "check" the 'constant is zero" box.
Instructions Part One: A linear regression analysis was performed in SPSS to evaluate the ability of independent variables full and part-time FTEs, number of Medicare certified beds and urban vs. rural setting to predict dependent variable, occupancy rate. In paragraph, APA-formatted form, interpret the results. Include basic assumptions for regression analysis.
