Statistic question. Please help. Part a,b,c is already answered. Need help with the remaining. Thank you
Given are five observations for two variables, and y. Use the estimated regression equation: = 67.5538 a. Compute the mean square error using equation. SSE s² = MSE= n 2 6.5289 (to 4 decimals) b. Compute the standard error of the estimate using equation. SSE 8 = √MSE = n-2 2.5552 (to 4 decimals) c. Compute the estimated standard deviation of b₁ using S Sb₁ = 59 S do Xi % Yi 2.6451, √√Σ(x₁ - x)² 0.1729 (to 4 decimals) d. Use the t-test to test the following hypotheses (α = 0.10): Ho: B1 = 0 Ha: B10 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 - # What is your conclusion? We Select your answer Ho. e. Use the F-test to test the hypotheses in part (d) at a 0.10 level of significance. 3 6 MacBook Pro 58 51 10 18 45 19 빈 20 14
