Question: Question 3 Suppose that the random variable X has the discrete uniform distribution f ( x ) = 1/4, x = 4, 5, 6, 7.

Question 3

Suppose that the random variable X has the discrete uniform distribution f ( x ) = 1/4, x = 4, 5, 6, 7. 0, otherwise. A random sample of n = 20 is selected from this distribution. Find the probability that the sample mean is greater than 5.8. Round your answer to two decimal places (e.g. 98.76). P = .46
