Compute the mean square error using equation. SSE = MSE п — 2 (to 4 decimals) b. Compute the standard error of the estimate using equation. SSE S = /MSE (to 4 decimals) c. Compute the estimated standard deviation of b1 using equation. S (æ; – 7)? (to 4 decimals) d. Use the t-test to test the following hypotheses (a = 0.10): Ho: B1 = 0 Ha: B1 + 0 Compute the value of the t-test statistic (Enter negative values as negative numbers). (to 3 decimals) What is the p-value? Use Table 2 from Appendix B. p-value is - Select your answer - 20 21
