Answer:
i. Girls : 10 merits
ii. Boys : 11.4 merits
iii. The boys did better on average because the number of their mean merits received is higher than that girls.
Step-by-step explanation:
Mean = 
Sum of merits received by boys = 5 + 10 + 19 + 22 + 13 + 10 + 1
= 80
number of merits = 7
Mean number of merits received by boys = 
= 11.4286
The mean number of merits received by boys is 11.4
Sum of merits received by girls = 6 + 11 + 15 + 16 + 12 + 10 + 0
= 70
number of merits = 7
Mean number of merits received by girls = 
= 10.0
The mean number of merits received by girls is 10.0
Therefore,
i. Girls : 10 merits
ii. Boys : 11.4 merits
iii. The boys did better on average because their mean merits is higher than that girls.
