Use the following set of points to test the null hypothesis H0: β1=0
Use the following set of points to test the null hypothesis H0: β1=0 versus H1: β1 ≠ 0. Use the critical value method with the α=0.05 level of significance. The slope of the regression line for this data is computed to be b1=-0.13834, and the standard error of b1 is computed to be sb=0.264048.x15173221210y81617161717Find the critical value(s). Round the answer to three decimal places. If there is more than one critical value, separate them with commas.Critical value(s):
