A multiple regression analysis produced the following tables: Using $\alpha$ = 0.05 to test the null hypothesis H₀: $\beta$₁ = 0, the critical t value is ___. A)± 1.753 B)± 2.110 C)± 2.131 D)± 1.740 E)± 2.500

Question

Quizplus · Accepted Answer

The critical t-value can be found using the F-distribution table with degrees of freedom given by (n-k-1) = 25-3-1 = 21 and the significance level of 0.05. This gives us an F-critical value of 2.131. Therefore, the critical t-value for a two-tailed test with 21 degrees of freedom and a significance level of 0.05 is ± 2.131. Therefore, the correct answer is C.
