Nationally, 38% of fourth-graders cannot read an age-appropriate book. The following data show the number of children, by age, identified as learning disabled under special education. Most of these children have reading problems that should be identified and corrected before third grade. Current federal law prohibits most children from receiving extra help from special education programs until they fall behind by approximately two years' worth of learning, and that typically means third grade or later (USA Today, September 6, 2001).

Age 6	Number of Children 37,369
7	87,436
8	160,840
9	239,719
10	286,719
11	306,533
12	310,787
13	302,604
14	289,168

Suppose that we want to select a sample of children identified as learning disabled under special education for a program designed to improve reading ability. Let x be a random variable indicating the age of one randomly selected child.

a. Use the data to develop a probability distribution for x. Specify the values for the ran- dom variable and the corresponding values for the probability function f (x).

b. Draw a graph of the probability distribution.

c. Show that the probability distribution satisfies equations (5.1) and (5.2).
