Question

Data from the Motor Vehicle Department indicate that 80% of all licensed drivers are older than age 25.

In a sample of n = 50 people who recently received speeding tickets, 33 were older than 25 years, and the other 17 were age 25 or younger. Is the age distribution for this sample significantly different from the distribution for the population of licensed drivers? Use α = .05.

Chi-Square Distribution

Degrees of Freedom = 16

Conclusion:

Fail to reject the null hypothesis; the distribution of ages for people who receive speeding tickets is not significantly different from that of the population of drivers.

Fail to reject the null hypothesis; the distribution of ages for people who receive speeding tickets is significantly different from that of the population of drivers.

Reject the null hypothesis; the distribution of ages for people who receive speeding tickets is not significantly different from that of the population of drivers.

Reject the null hypothesis; the distribution of ages for people who receive speeding tickets is significantly different from that of the population of drivers.
