Option 4
Step-by-step explanation:
Group B, because seven children have a forearm length longer than 10 inches.
Additional verification :
Finding average forearm length of Group A :
- 9(3) + 10(5) + 11(2) / 10
- 27 + 50 + 22 / 10
- 99/10
- 9.9
Finding average forearm length of Group B :
- 10(3) + 11(4) + 12(3) / 10
- 30 + 44 + 36 / 10
- 100/10
- 10
Group B clearly has the longer forearm length.
