Among 450 randomly selected drivers in the 20-24 age bracket, 20 were involved in a car crash in the last year. If a driver in this age bracket is randomly selected, what is the approximate probability that he or she will be involved in a car crash during the next year? Is it unlikely for a driver in this age bracket to be involved in a car crash during the year? Is the resulting value high enough to be of concern in the 20-24 age bracket? Consider using the Chi-Square Distribution with a significance level equal to 0.05. Probability that a randomly selected person in the 20-24 age bracket will car crash this year is approximately (Type as an integer or decimal rounded to the nearest thousandth as needed). Would it be unlikely for a driver in this age bracket to be involved in a car crash this year? Is the probability high enough to be of concern to those in the 20-24 age bracket?
