Question

if the standard deviation of chi square distribution is 10 then its degree of freedom is
​

Answer 1

Χ²10

Step-by-step explanation:

Given: Standard deviation of chi square distribution is 10.

Find: Degree of freedom.

Solution:

Degrees of freedom are placed as a subscript after the chi-square (Χ²) symbol.

For example, the following chi square shows 6 degrees of freedom (df): Χ²6.

And this chi square shows 4 df: Χ²4.

For the χ2 distribution, the population mean is μ = df and the population standard deviation is σχ2=√2(df) σ χ 2 = 2 (df)

So the degree of freedom of the given chi-square distribution = 10
