Question

R² = 0.5754 and n = 425. The chi-square statistic for testing the overall regression effect H₀ for both slopes is 0. 575.9421:

How many degrees of freedom are there for the chi-square test statistic?

Answer 1

Answer #1

Answer:

Given data

n = 425

R2 = 0.5754

We have to find the How many degrees of freedom are there for the chi-square test statistic:

We know that

The formula of degrees of freedom is given by

Degrees of freedom (df) = n-1

Degrees of freedom (df) = 425-1

Degrees of freedom (df) = 424

Therefore the "424" degrees of freedom are there for the chi-square test statistic.
