# Statistics - Chi-square distribution

A) Suppose that X 2nd power follows a chi-square distribution with 11 degrees of freedom. Compute P(x 2nd power lesser than or equal to 8). Round your answer to at least three decimal places.

b) Suppose again that X 2nd power follows a chi-square distribution with 11 degrees of freedom. Find k such that P(X 2nd power greater than k) = 0.025. Round your answer to at least two decimal places.

c) Find the median of the chi-square distribution with 11 degrees of freedom. Round your answer to at least two decimal places.
