Solution

Relative Humidity (in $%$ ) Frequency
$84 - 86$ $1$
$86 - 88$ $1$
$88 - 90$ $2$
$90 - 92$ $2$
$92 - 94$ $7$
$94 - 96$ $6$
$96 - 98$ $7$
$98 - 100$ $4$
$Total$ $30$
(i) The table above is the frequency distribution.
(ii) The data appears to be taken in the rainy season as the relative humidity is high.
(iii) Range of data $=$ Maximum value - Minimum value $= 99.2 - 84.9 = 14.3$
