Question

Suppose the percent of licensed U.S. drivers (from a recent year) that are female is 48.30. Of the females, 6.02% are age 19 and under; 80.79% are age 20-64; 13.19% are age 65 or over. Of the licensed U.S. male drivers, 5.68% are age 19 and under; 79.86% are age 20-64; 14.46% are age 65 or over.

Suppose that 10,000 U.S. licensed drivers are randomly selected.

Part (a)

How many drivers would you expect to be male?
drivers
Part (b)

Using a tree diagram of the given situation, construct a contingency table of gender versus age group. (Round your answers to the nearest whole number.)

19 and under 20-64 65 and over Total

Female

Male

Total 10,000
Part (c)

Using a contingency table, find the probability that out of the age 20-64 group, a randomly selected driver is female. (Round your answer to two decimal places.)
