Question

The number of drivers fined for breaking traffic rules on each day in June at a certain square is as follows-
$\begin{array}{ccccccccccccccc}2& 0& 3& 2& 3& 1& 3& 0& 2& 1& 1& 2& 2& 3& 1\\ 0& 1& 0& 4& 3& 2& 1& 2& 3& 3& 2& 3& 4& 4& 2\end{array}$

From this data, make a frequency table and find the mean.

Answer 1

$$\begin{gathered} \overline{\mathrm{X}}=\frac{\mathrm{Total}\left(x\times f\right)}{\mathrm{N}} \\ =\frac{60}{30} \\ =2 \end{gathered}$$
Hence, the mean is 2.
