Section 4.1 Homework

8. 

Among 450 randomly selected drivers in the 16−18 age​ bracket, 228

were in a car crash in the last year. If a driver in that age bracket is randomly​ selected, what is the approximate probability that he or she will be in a car crash during the next​ year? Is it unlikely for a driver in that age bracket to be involved in a car crash during a​ year? Is the resulting value high enough to be of concern to those in the 16−18 age​ bracket? Consider an event to be​ “unlikely” if its probability is less than or equal to 0.05.

The probability that a randomly selected person in the 16−18 age bracket will be in a car crash this year is approximately _______

Would it be unlikely for a driver in that age bracket to be involved in a car crash this​ year?

1. No
2. Yes

Is the probability high enough to be of concern to those in the 16−18 age​ bracket?

1. Yes
2. No
