Heights of People
For $200$ people, their exact height $x$ in centimetres is measured.
The observations are grouped as follows:
$\begin {array} {r|l} \hline \text {Height $x$ (cm)} & \text {Count} \\ \hline x < 165 & 6 \\ 165 \le x < 170 & 39 \\ 170 \le x < 175 & 93 \\ 175 \le x < 180 & 44 \\ 180 \le x < 185 & 15 \\ x \ge 185 & 3 \\ \hline \end {array}$
