# Chi Square Distribution

Chi-square distribution

Use the calculator provided to solve the following problems.

?Suppose that X2 follows a chi-square distribution with 7 degrees of freedom. Compute P (X2 <=5). Round your answer to at least three decimal places.

?Suppose again that X2 follows a chi-square distribution with 7 degrees of freedom. Find k such that P (X2 > k) = 0.1. Round your answer to at least two decimal places.

?Find the median of the chi-square distribution with 7 degrees of freedom. Round your answer to at least two decimal places.
