Let X be a random variable from a Chi-Square Distribution with 13 degrees of freedom. Tatiana is interested in the random variable Y = aX+b. She knows that E(Y) = 24 and V(Y) = 416. What are all possible values of a and b that satisfy this criteria? Write your answer as an ordered pair, (a, b). If there are multiple solutions, separate the ordered pairs by a comma.
