World music paper... Suppose x has a distribution with a mean of 50 and a standard deviation of 4. Random samples of size n = 64 are drawn. (a) Describe the x distribution. O x has a binomial distribution. O x has a normal distribution. O x has a Poisson distribution. O x has a geometric distribution. O x has an approximately normal distribution. O x has an unknown distribution. X Compute the mean and standard deviation of the distribution. (For each answer, enter a number.) Hy = = (b) Find the 2 value corresponding to x = 49. (Enter an exact number.) 2 = (c) Find P(x
