Given are five observations for two variables, x and y. Excel File: data14-25.xlsx 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)? b. Test for a significant relationship by using the t test. Use α = 0.05. What is the value of the t test statistic (to 2 decimals)? What is the p-value?
