Magnetic resonance imaging (MRI) is a process that produces internal body images using a strong

magnetic field. Some patients become claustrophobic and require sedation because they are required to lie

within a small, enclosed space during the MRI test. Suppose that 20% of all patients undergoing MRI testing

require sedation due to claustrophobia. If five patients are selected at random, find the probability that

the number of patients in these five who require sedation is

a. exactly 2 b. none c. exactly 4

According to a March 25, 2007 Pittsburgh Post-Gazette article, 30% to 40% of U.S. taxpayers cheat

on their returns. Suppose that 30% of all current U.S. taxpayers cheat on their returns. Use the binomial

probabilities table (Table I of Appendix C) or technology to find the probability that the number of U.S.

taxpayers in a random sample of 14 who cheat on their taxes is

a. at least 8 b. at most 3 c. 3 to 7

In a 2009 poll of adults 18 years and older, (BBMG Conscious Consumer Report) about half of

them said that despite tough economic times, they are willing to pay more for products that have social

and environmental benefits. Suppose that 50% of all such adults currently hold this view. Suppose that

a random sample of 20 such adults is selected. Use the binomial probabilities table (Table I of Appendix

C) or technology to find the probability that the number of adults in this sample who hold this

opinion is

a. at most 7 b. at least 13 c. 12 to 15

An object with a mass of 0.5 kilogram is swung by a string in a horizontal circle of radius 1 meter at a speed of 2 meters per second. The magnitude of the force on the mass is

According to a National Public Radio poll, 46% of American school principals believe that students

pay little or no attention to sex education provided in schools (http://www.npr.org/programs/morning/

features/2004/jan/kaiserpoll/principalsfinal.pdf). Suppose that this result is true for the current population

of American school principals.

a. Let x be a binomial random variable denoting the number of American school principals in a random

sample of 11 who believe that students pay little or no attention to sex education taught in

schools. What are the possible values that x can assume?

b. Find the probability that in a random sample of 11 American school principals, exactly 3 believe

that students pay little or no attention to sex education taught in schools.

According to a Harris Interactive poll, 52% of American college graduates have Facebook accounts

(http://www.harrisinteractive.com/harris_poll/pubs/Harris_Poll_2009_04_16.pdf). Suppose that this result

is true for the current population of American college graduates.

a. Let x be a binomial random variable that denotes the number of American college graduates in

a random sample of 15 who have Facebook accounts. What are the possible values that x can

assume?

b. Find the probability that exactly 9 American college graduates in a sample of 15 have Facebook

accounts.
