Question

Using multiple regression for a data set with 30 observations, the following estimated regression equation was developed: $\hat{y} = 4.67 + 2.09x_1 - 0.73x_2 + 3.41x_3$ Use t-table to find the critical value for a test of significance of parameter $\beta_3$ in the corresponding multiple regression equation; use $\alpha = 1\%$ and show your answer with three decimal places.

Step 1

In this case, n = 30 and k = 3, so the degrees of freedom is 30 - 3 - 1 = 26. Show more…
