Ответ:
Option b = 90 degrees of freedom.
Step-by-step explanation:
So, in this particular Question we are given the following parameters or data or information which is going allow us to be able to solve this particular problem or Question;
=> "A regression analysis involved 8 independent variables"
=> "99 observations. "
Requirement : to determine the critical value of t for testing the significance of each of the independent variable's coefficient.
Hence, the formula below will used in Calculating or in the determination of the degree of freedom;
Degree of freedom= total number of observations - number of independent variables- 1.
Thus, slotting bin the values into the formula above, we have;
The degree of freedom = 99 - 8 - 1 = 90.
