Refer to the ANOVA table for this regression. Source Regression Error df sS INS 3 1,113,914 371,305 301,348 28 1,415,262 23 13,102 Total (a) State the degrees of freedom for the F test for overall significance. degrees of freedom for regression are and for e (b) Use Appendix-to look up the critical value of F for = .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 O No (c-3) The hypotheses are aHo: All the coefficients are zero (61-62-63 = 0) vs. H,At least one coefficient is not zero. b·Ho: At least one coefficient is non-zero vs. H!: All the coefficients are zero (.- o b (d) Calculate R and R a (Round your answers to 4 decimal places.) adj

Explanation / Answer

a) Degree of freedom for Regression is 3 and for error is 23

b) Critical value will be 3.03

c) F statistic = 371305/13102 = 28.340

d2) Yes, overall regression is significant
