Interpreting Summary Output for Simple Linear Regression

Interpreting Summary Output for Simple Linear Regression
(Round all calculations to 4 places.)

Using the second attached BALDOR data and Excel output, complete the following:

1. What is the value of the correlation coefficient?

2. What is the value of the coefficient of determination?

3. What is the value of the y-intercept of the regression (prediction) line?

4. What is the value of the slope of the regression (predictions) line?

5. Write the prediction equation for this set of data.

6. Is the prediction equation significant?

7. Is the correlation coefficient significant (p < .05)?

8. What percent of the variation in the dependent variable (y) is explained (accounted for) by the independent variable (x)?

9. Compute predicted y for x = 10.
