The degrees of freedom of Chi-square variate is 7. Find its Mean, mode

1.	The degrees of freedom of Chi-square variate is 7. Find its Mean, mode and variance.
Answer» n = 7, mean = n = 7, Mode = (n – 2) = 5 and Variance = 2n = 2 × 7 = 14.

The degrees of freedom of Chi-square variate is 7. Find its Mean, mode and variance.

Answer»

n = 7, mean = n = 7, Mode

= (n – 2) = 5 and Variance

= 2n = 2 × 7 = 14.
