Probability Distribution I A random variable x has this probability distribution:

a. Find p(4).

b. Construct a probability histogram to describe p(x).

c. Find µ, σ², and σ.

d. Locate the interval µ ± 2 σon the x-axis of the histogram. What is the probability that x will fall into this interval?

e. If you were to select a very large number of values of x from the population, would most fall into the interval µ ± 2σ? Explain.
