A regression analysis involved 5 independent variables and 99 observations. The critical value of t for testing the significance of each of the independent variable's coefficients will have _____ degrees of freedom.
A) 98
B) 93
C) 90
D) 4

Question

Quizplus · Accepted Answer

The degrees of freedom for testing the significance of an independent variable's coefficient in a regression analysis is calculated as the number of observations minus the number of parameters being estimated (including the intercept). Here, with 99 observations and 5 independent variables plus 1 intercept, the degrees of freedom = 99 - (5 + 1) = 93.
