Question

Whenever the calculated value of t is less than the tabled value of t (for a given number of degrees of freedom), then

A.) We fail to reject Ho

B.) Ho is rejected

C.) Ho is no longer relevant

D.) the alpha level increases

Answer 1

A.) We fail to reject Ho

To determine whether to reject the null hypothesis using the t-value, compare the t-value to the critical value. The critical value is tα/2, n–p-1, where α is the significance level, n is the number of observations in your sample, and p is the number of predictors.

If the absolute value of the t-value is greater than the critical value, you reject the null hypothesis. If the absolute value of the t-value is less than the critical value, you fail to reject the null hypothesis.
