The analyst would like to build a multiple regression model to estimate the annual nursing salaries (Y) that should be expected for each facility.

1. Prepare scatter plots showing the relationship between the nursing salaries and each of the independent variables. What sort of relationship does each plot suggest?
2. If the budget analyst wanted to build a regression model using only one independent variable to predict the nursing home salaries, what variable should be used?
3. If the budget analyst wanted to build a regression model using only two independent variables to predict the nursing home salaries, what variables should be used?
4. If the budget analyst wanted to build a regression model using only three independent variables to predict the nursing home salaries, what variables should be used?
5. What set of independent variables results in the highest value for the adjustment statistic?
6. Suppose the personnel director chooses to use the regression function with all independent variables , , and . What is the estimated regression function?
