An auditor for a local court system is tasked with comparing the rulings of two judges. The auditor needs to determine if Judge Hughes issues shorter sentences than Judge Wilson. The data below are the sentence lengths, in months, issued by each judge in their last twelve cases that dealt with operating a motor vehicle without a license. Test the claim that Judge Hughes issues shorter sentences than Judge Wilson for this particular type of case at the 0.10 level of significance. Let Judge Hughes' sentences be Population 1 and let Judge Wilson's sentences be Population 2. Assume that both populations are approximately normal and that the population variances are equal.
| Judge Hughes | 36 | 12 | 30 | 24 | 30 | 18 | 12 | 12 | 24 | 12 | 24 | 36 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Judge Wilson | 36 | 18 | 36 | 30 | 12 | 24 | 30 | 24 | 30 | 36 | 30 | 30 |
Step3of3: Draw a conclusion and interpret the decision.
A,) We reject the null hypothesis and conclude that there is insufficient evidence at a 0.10 level of significance to say thatJudge Hughes issues shorter sentences than Judge Wilson.
B.) We fail to reject the null hypothesis and conclude that there is insufficient evidence at a 0.10 level of significance to say thatJudge Hughes issues shorter sentences than Judge Wilson.
C.) We reject the null hypothesis and conclude that there issufficientevidence at a 0.10 level of significance to say thatJudge Hughes issues shorter sentences than Judge Wilson.
D.) We fail to reject the null hypothesis and conclude that there is sufficient evidence at a 0.10 level of significance to say thatJudge Hughes issues shorter sentences than Judge Wilson.
