Given are five observations for two variables, and y. Excel File: data14-25.xlsx What is the value of the t test statistic (to 2 decimals)? 1.90 What is the p-value? Use Table 2 of Appendix B. The estimated regression equation is ŷ = 7.6 +0.9x. a. What is the value of the standard error of the estimate (to 4 decimals)? 0.9726 b. Test for a significant relationship by using the t test. Use a = 0.05. between 0.10 and 0.20 What is your conclusion (α = 0.05)? Xi Yi 8 3.63 What is the p-value? Use Table 4 of Appendix B. Cannot conclude a significant relationship exists between x and y c. Use the F test to test for a significant relationship. Use a = 0.05. Compute the value of the F test statistic (to 2 decimals). greater than 0.10 What is your conclusion? Cannot conclude a significant relationship exists between x and y 2 7 6 9 13 20 18 9 26 23
