2003, the average combined SAT score (math and verbal) for college-bound students in the United States was 1,026. Suppose that approximately 45% of all high school graduates took this test and that 100 high school graduates are randomly selected from among all high school grads in the United States. Which of the following random variables has a distribution that can be approximated by a binomial distribution? Whenever possible, give the values for n and p.

In 2003, the average combined SAT score (math and verbal) for college-bound students in the United States was 1,026. Suppose that approximately 45% of all high school graduates took this test and that 100 high school graduates are randomly selected from among all high school grads in the United States. Which of the following random variables has a distribution that can be approximated by a binomial distribution? Whenever possible, give the values for n and p.

(d) the amount of time required by each student to complete the SAT
O binomial with n = 100 and p = 0.45
O binomial with n = all college-bound students in the United States andp = proportion of students of high school students who scored above 1,026
O binomial with n = 100 and p = proportion of students of high school students who scored above 1,026
O binomial with n = all college-bound students in the United States andp = 0.45
O not a binomial random variable
(e) the number of female high school grads in the sample
O binomial with n = 100 and p = 0.45
O binomial with n = all college-bound students in the United States andp = proportion of students of high school students who scored above 1,026
O binomial with n = 100 and p = proportion of students of high school students who scored above 1,026
O binomial with n = all college-bound students in the United States andp = 0.45
O not a binomial random variable
