Given are five observations for two variables, & and y. 2 i 3 8 12 15 17 Yi 53 52 40 17 13 Use the estimated regression equation: ☺ = 69.3968 – 3.1270x. a. Compute the mean square error using equation. SSE $2 = MSE = n - 2 (to 4 decimals) b. Compute the standard error of the estimate using equation. SSE S=V MSE n - 2 (to 4 decimals) c. Compute the estimated standard deviation of bị using equation. S Sb= (xi – 7)? (to 4 decimals) d. Use the t-test to test the following hypotheses (a=0.10): Ho: Bl=0 He: B170 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 -
Compute the value of the t-test statistic (Enter negative values as negative numbers). (to 3 decimals) 3 What is the p-value? Use Table 2 from Appendix B. p-value is - Select your answer - V What is your conclusion? We - Select your answer - v Ho. e. Use the F-test to test the hypotheses in part (d) at a 0.10 level of significance. Complete the F table below using Excel. Calculate the Sum of Squares (to 1 decimal), the Mean Squares (to 1 decimal), and the F ratio (to 2 decimals) and the p-value (to 4 decimals). Source Sum of Mean Degrees of Freedom of Variation Squares Square F p-value Regression Error Total What is your conclusion, based on this F test? We Select your answer - v H.
