9.20 let x be chi-squared with k = 5 degrees of freedom. (a) what is p[x > 1]? (this exact calculation requires some serious integration) (b) find p[x > 1] with the normal approximation, i. e., approximate the probability assuming x ~ n(mu, sigma squared), where mu and sigma squared are the mean and variance of a gamma(5/2, 1/2).

Will mark brainliest for correct answer! i have been on this problem for an hour and can't find the answer. i'm begging here! incase you cant read the instructions in the picture because of too much or too little lighting: note: enter your answer and show all the steps that you use to solve this problem in the space provided.write a list of steps that are needed to find the measure of b. provide all steps as clear as possible, !
