Show SolutionHide Solution↓

Correct table
$\Rightarrow \text{Mean} = \frac{2830}{80}$
$= 35.375$
Modal class = $(35 - 45)$
$\Rightarrow \text{Mode} = 35 + \left(\frac{23-21}{2\times23-21-14}\right) \times h$
$= 36.81$
Therefore, mode and mean of given data are $36.81$ years and $35.375$ years respectively.
