(a) Describe the x distribution. O x has a normal distribution. O x has a Poisson distribution. O x has an unknown distribution. O x has a binomial distribution. O x has a geometric distribution. O x has an approximately normal distribution. Compute the mean and standard deviation of the distribution. (For each answer, enter a number.) Hy = (b) Find the z value corresponding to x = 47. (Enter an exact number.) z= (c) Find P(x
