Help with this math equation please help
Alex787 [66]

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 = \frac{sum of merits}{number of merits}

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 = \frac{80}{7}

                                           = 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 = \frac{70}{7}

                                             = 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.
