Suppose x has a distribution with a mean of 60 and a standard deviation of 21, Random samples of size n = 36 are drawn. (a) Describe the x distribution. x has an approximately normal distribution. O x has a Poisson distribution. O x has an unknown distribution. O x has a normal distribution. O x has a binomial distribution. O x has a geometric distribution. Compute the mean and standard deviation of the distribution. (For each answer, enter a number.) Hy = 60 Oy = 3.5 (b) Find the z value corresponding to x = 67- (Enter an exact number.) 2= (c) Find P(x
