Critical value of t for testing the significance of each of the independent variable's coefficients will have 679 degree of freedom.
We are given the following parameters or data or information
"A regression analysis involved 17 independent variables", "697 observations. "
Number of observations = 697
Number of independent variables = 17
In regression, the critical value t for testing the significance of variable's coefficients has the number of degrees of freedom formula which is (number of observations) - (number of independent variables + 1).
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 = (number of observations) - (number of independent variables + 1).
Thus, slotting bin the values into the formula above, we have;
The degree of freedom = 697 - (17 +1) = 679
