In order to test for the significance of a regression model involving 14 independent variables and 255 observations, the numerator and denominator degrees of freedom for the critical value of the fare is:___________.
A. 14 and 255
B. 255 and 14
C. 13 and 240
D. 14 and 240

Respuesta :

Answer:

C; 13 and 240

Step-by-step explanation:

Here in this question, we are to give the numerator and the denominator degrees of freedom.

Mathematically;

the numerator degrees of freedom = number of variables - 1 = 14 -1 = 13

The numerator degrees of freedom = number of observations- numerator degrees of freedom - 1

= 255 - 14-1 = 255-15 = 240

The critical value of the fare is options c. 13 and 240.

Calculation of the critical value:

Since the numerator degrees of freedom should be

= number of variables - 1

= 14 -1

= 13

Now

The numerator degrees of freedom should be

= number of observations- numerator degrees of freedom - 1

= 255 - 14-1

= 255-15

= 240

Therefore, the correct option is c.
