Problem
The table at the bottom of the page summarizes data on smoking status and perceived risk of smoking and is consistent with summary quantities obtained in a Gallup Poll conducted in November 2002. Assume that it is reasonable to consider these data as representative of the adult American population.
a. What is the probability that a randomly selected adult American is a former smoker?
b. What is the probability that a randomly selected adult American views smoking as very harmful?
c. What is the probability that a randomly selected
Regularly
Assume that these proportions are representative of adult Americans and that an adult American is selected at random.
a. What is the probability that the selected adult regu- larly uses a seat belt?
b. What is the probability that the selected adult regu- larly uses a seat belt given that the individual selected is male?
c. What is the probability that the selected adult does not use a seat belt regularly given that the selected individual is female?
d. What is the probability that the selected individual is female given that the selected individual does not use a seat belt regularly?
e. Are the probabilities from Parts (c) and (d) equal? Write a couple of sentences explaining why this is so.
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
