Complete Exercise 14.12 (The Fresh Detergent Case) on page 575 in your textbook
Above each output we give the regression model and the number of observations, n, used to perform the regression analysis under consideration. Using the appropriate model, sample size n, and output:
1)Report SSE, s2, and s as shown on the output. Calculate s2 from SSE and other numbers.
2)Report the total variation, unexplained variation, and explained variation as shown on the output.
3)Report R2 and are?2 as shown on the output. Interpret R2 and are?2. Show how are?2 has been calculated from R2 and other numbers.
4)Calculate the F (model) statistic by using the explained variation, the unexplained variation, and other relevant quantities. Find F (model) on the output to check your answer (within rounding).
5)Use the F (model) statistic and the appropriate critical value to test the significance of the linear regression model under consideration by setting ? Equal to .05.
6)Use the F (model) statistic and the appropriate critical value to test the significance of the linear regression model under consideration by setting ? Equal to .01.
7)Find the p-value related to F (model) on the output. Using the p-value, test the significance of the linear regression model by setting ? = .10, 05, 01, and .001. What do you conclude?
Model: why = ?0 ?1 x1 ?2 x2 ?3 x3 ?you Sample size: n = 30
