Answer:
2.9
Step-by-step explanation:
the mean number is (total number of children / number of households)
to find the total number of children, multiply the number of households by the number of children per household in each row and add them together
total number of children = (9*4)+(14*2)+(14*3) = 106
number of households = 9+14+14 = 37
mean = 106/37 = 2.86486
which rounds to 2.9
