Suppose X is a normal random variable with mean µ = 44 and standard deviation a = 7. (a) Compute the z-value corresponding to X = 33. (b) Suppose the area under the standard normal curve to the left of the z-value found in part (a) is 0.0580. What is the area under the normal curve to the left of X=337 (c) What is the area under the normal curve to the right of X=33? (a) z = -1.57 (Round to two decimal places as needed.) (b) The area is (Round to four decimal places as needed.) Suppose X is a normal random variable with mean µ = 44 and standard deviation a = 7. (a) Compute the z-value corresponding to X = 33.
