## nuccioreggie one year ago The table below shows the size of nine families selected at random from two neighborhoods in a large city: Family Size (in number of people) Neighborhood Q 2 5 4 3 2 5 3 6 5 Neighborhood S 2 3 2 3 7 2 3 3 2 Which neighborhood appears to have a bigger family size? Explain your answer using two or three sentences.

here you have to compute the subsequent mean values: $\Large \begin{gathered} {m_1} = \frac{{2 + 5 + 4 + 3 + 2 + 5 + 3 + 6 + 5}}{9} = ... \hfill \\ \hfill \\ {m_2} = \frac{{2 + 3 + 2 + 3 + 7 + 2 + 3 + 3 + 2}}{9} = ... \hfill \\ \end{gathered}$
