Question

In order to test for the significance of a regression model involving 4 independent variables and 47 observations, the numerator and denominator degrees of freedom (respectively) for the critical value of F are Select one: a. 3 and 43 b. 4 and 43 c. 4 and 42 d. 3 and 42

Answer 1

c. 4 and 42

Explanation:

Given

`p = 4` -- independent variables

`n = 47` ---- observations

Required

The numerator and denominator degrees of freedom

The denominator degrees of freedom is:

`df =n - p - 1`

`df =47 - 4 - 1`

`df =42`

For the numerator, we have:

`df = p`

`df = 4`
