Among 400 randomly selected drivers in the 16 minus 18 age bracket, 293 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 minus 18 age bracket? Consider an event to be "unlikely" if its probability is less than or equal to 0.05.

The approximate probability is 0.7325.

Is not unlikely that a driver in that age bracket is involved in a car crash during a year, so there are reasons to be concerned.

Step-by-step explanation:

The approximate probability can be estimated using the sample proportion:

A probability of 0.7325 is high, so it is not unlikely that a driver in that age bracket is involved in a car crash during a year.

As this value is high, there is reasons to be concerned about it.

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
