Question

The regression equation is $\hat{Y} = 29.29 - 0.90X$, the sample size is 26, and the standard error of the slope is 0.22. What is the critical value to test whether the slope is different from zero at the 0.01 significance level? a. $z = \pm 1.416$ b. $t = \pm 2.797$ c. $z = \pm 1.666$ d. $t = \pm 2.445$

Step 1

Since we are testing the slope of a regression line, we will use a t-distribution. The degrees of freedom are $df = n - 2 = 26 - 2 = 24$. Show more…
