A multiple 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

Answer:196Step-by-step explanation:Formula of degree of freedom for simple regression = n-2Formula of degree of freedom for multiple regression = n-k-1We are given the case of multiple regression and there are three independent variables.So, k = 3n = 200So, Degree of freedom for multiple regression =[tex]n-k-1[/tex]                                                                               = [tex]200-3-1[/tex]                                                                               = [tex]196[/tex]So, Option A is true .Hence degrees of freedom for testing the statistical significance of individual slope coefficients is 196
