Question

Quizplus · Accepted Answer

The critical t value is determined by the degrees of freedom (df) for the regression model. To calculate df, we need to subtract the number of independent variables from the total sample size minus one: df = n - k - 1 = 30 - 3 - 1 = 26. With an alpha level of 0.05 and 26 df, the critical t value is ±2.131. Therefore, the best choice is C.
