Answer 1

Neighborhood Q
6 ; 3 ; 1 ; 2 ; 3 ; 2 ; 5 ; 1 ; 2 (9 families in total)
Neighborhood S
5 ; 2 ; 4 ; 3 ; 5 ; 3 ; 2 ; 4 ; 5 (9 families in total as well)

Which neighborhood appears to have a bigger family size?

well to determine that, we have to find the average people per family


Neighborhood Q= \(\frac{6 + 3 + 1 + 2 + 3 + 2 + 5 + 1 + 2}{9} \Rightarrow \frac{25}{9} \)


Neighborhood S=\( \frac{5 + 2 + 4 + 3 + 5 + 3 + 2 + 4 + 5 }{9}\Rightarrow \frac{33}{9}\)


so, which of the neighborhoods has got the bigger family size?
