In Question 16, you tested for a relationship between black and Hispanic juveniles in terms of the length of probation sentences received. Now let's find out whether there is a between-group difference among those sentenced to community service. The following table shows pairs of youths matched on gender (male) and offense type (weapons). Using an alpha level of .05, test the hypothesis that there is a statistically significant difference between the groups' means. Use all five steps.

Pair	Community-Service Sentence (hours)
Black	Hispanic
Pair A	25	30
Pair B	50	40
Pair C	48	50
Pair D	100	110
Pair E	40	30
