Amultiple regression model using 200 data points (with three independent variables) has how many degrees of freedom for testing the statistical significance of individual slope coefficients?
196
199
198

196

Step-by-step explanation:

Formula of degree of freedom for simple regression = n-2

Formula of degree of freedom for multiple regression = n-k-1

We are given the case of multiple regression and there are three independent variables.

So, k = 3

n = 200

So, Degree of freedom for multiple regression =

                                                                              =

                                                                              =

So, Option A is true .

Hence degrees of freedom for testing the statistical significance of individual slope coefficients is 196
