Question

Refer to the ANOVA table for this regression. Source Regression Error d.f MS 3 1,196,410 398,803 26 29 1,575,742 379,332 14,590 Total XC (a) State the degrees of freedom for the F test for overall significance The degrees of freedom for regression are and for error (b) Use Appendix F to look up the critical value of F for a.05. (Round your answer to 2 decimal places.) 05 (c-1) Calculate the F statistic. (Round your answer to 3 decimal places.) F statistic (c-2) The overall regression is significant. O Yes 0 (c-3) The hypotheses are a. Ho: All the coefficients are zero (81 ?2-?3-0) vs. H1: At least one coefficient is not zero b. Ho: At least one coefficient is non-zero vs. H1: All the coefficients are zero (31230) (d) Calculate R2 and R2 adjs (Round your answers to 4 decimal places.)

Explanation / Answer

a.) Degree of Freedom for Regression: 3

Degree of Freedom for Error: 26

b.) Critical value for F0.05 is: 2.98
