Question:
If the heights of 5 persons are 140 cm, 150 cm, 152 cm, 158 cm and 161 cm respectively. Find the mean height.
Solution:
Given: The heights of 5 persons are 140 cm, 150 cm, 152 cm, 158 cm and 161 cm
$\therefore$ Mean Weight $=\frac{\text { Sum of heights }}{\text { Total no. of persons }}$
$=\frac{140+150+152+158+161}{5}$
$=\frac{761}{5}=152.2$
