Multiple Choice

For a set of 30 data points, Excel has found the estimated multiple regression equation to be $\hat { y }$ = ?8.61 + 22x1 + 7x2 + 28x3, and has listed the t statistic for testing the significance of each regression coefficient. Using the 5% significance level for testing whether ?3 = 0, the critical region will be that the absolute value of the t statistic for ?3 is greater than or equal to:
