Question

Assume a member is selected at random from the population represented by the graph. Find the probability that the member selected at random is from the shaded area of the graph. Assume the variable x is normally distributed.

SAT Critical Reading Scores 200800400Score mu equals 504μ=504 sigma equals 119σ=119 200 less than x less than 400200<x<400 x A graph titled S A T Critical Reading Scores has a normal curve over a horizontal x-axis labeled Score from less than 200 to more than 800. Vertical line segments extend from the horizontal axis to the curve at 200 and 400, where 400 is to the left of center. The area under the curve between 200 and 400 is shaded and labeled 200 less than x less than 400. The equations mu equals 504 and sigma equals 119 are displayed on the graph.

The probability that the member selected at random is from the shaded area of the graph is

nothing.
