To test the fairness of law enforcement in its area, a local citizens' group wants to know whether women and men are unequally likely to get speeding tickets. Four hundred randomly selected adults were phoned and asked whether or not they had been cited for speeding in the last year. Using the results in the following table and a 0.01 level of significance, test the claim of the citizens' group. Let men bePopulation 1 and let women be Population 2.
Speeding Tickets:
Ticketed | Not Ticketed | |
Men | 20 | 167 |
Women | 11 | 202 |
Step3of3:
Draw a conclusion and interpret the decision.
A.) We fail to reject the null hypothesis and conclude that there is sufficient evidence at a 0.01 level of significance tosupport the local group's claim that women and men are unequally likely to get speeding tickets.
B.) We fail to reject the null hypothesis and conclude that there is insufficient evidence at a 0.01 level of significance tosupport the local group's claim that women and men are unequally likely to get speeding tickets.
C.) We reject the null hypothesis and conclude that there is insufficient evidence at a 0.01 level of significance tosupport the local group's claim that women and men are unequally likely to get speeding tickets.
D.) We reject the null hypothesis and conclude that there is sufficient evidence at a 0.01 level of significancetosupport the local group's claim that women and men are unequally likely to get speeding tickets.
