For Exercises 34–39, apply the Strategy for Building a Multiple Regression Model by performing the following steps, using level of significance :

  1. Step 1 Perform the test for significance of the overall regression.
  2. Step 2 Perform the tests for the individual predictors. If at least one of the predictors is not significant, then eliminate the variable with the largest -value from the model. Repeat Step 2 until all remaining predictors are significant.
  3. Step 3 Verify the assumptions.
  4. Step 4 Report and interpret your final model. Report and interpret the coefficients, the standard error of the estimate , and the adjusted coefficient of determination .
