Let X be a random variable from a Chi-Square Distribution with 13 degrees of freedom. Jada is interested in the random variable Y = aX+b. She knows that E(Y) = 26 and V (Y) = 416. Jada wants to find out 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. Hint: Use properties of expected value and variance to find a and b.
