Exercise 5.3

Suppose x is a random variable best described by a uniform probability distribution with c = 10 and d = 30.

a. Find f(x).

b. Find the mean and standard deviation of x.

c. Graph f(x), and locate μ and the interval μ ±2σ on the graph. Note that the probability that x assumes a value within the interval μ ±2σ is equal to 1.
