the graph shows the effect of the number of passengers on the number of crashes per 10,000 trips. about how many times more likely is a 17 - year - old driver to crash with three passengers than with one passenger? crashes by number of passengers and driver age 0 1 2 3+ about twice as likely about three times as likely about four times as likely about five times as likely crashes per 10,000 trips 7 6 5 4 3 2 1 0 drivers ages 16 - 17 number of passengers
Answer
Answer:
about four times as likely
Explanation:
Step1: Estimate crashes with 1 passenger
From the bar - graph, for 16 - 17 year - old drivers with 1 passenger, the number of crashes per 10,000 trips is approximately 2.
Step2: Estimate crashes with 3+ passengers
For 16 - 17 year - old drivers with 3+ passengers, the number of crashes per 10,000 trips is approximately 8.
Step3: Calculate the ratio
To find out how many times more likely a 17 - year - old driver is to crash with three passengers than with one passenger, we calculate the ratio $\frac{\text{Crashes with 3 + passengers}}{\text{Crashes with 1 passenger}}=\frac{8}{2}=4$. So a 17 - year - old driver is about four times as likely to crash with three passengers than with one passenger.
