Question

The relative humidity (in %) of a certain city for a September month of $30$ days was as follows:

$98.1$	$98.6$	$99.2$	$90.3$	$86.5$	$95.3$	$92.9$	$96.3$	$94.2$	$95.1$
$89.2$	$92.3$	$97.1$	$93.5$	$92.7$	$95.1$	$97.2$	$93.3$	$95.2$	$97.3$
$96.0$	$92.1$	$84.9$	$90.0$	$95.7$	$98.3$	$97.3$	$96.1$	$92.1$	$89$

What is the range of the data?

Answer 1

Relative humanity (in %) Tally No of days ( frequency)

$84-86$ I $1$

$86-88$ I $1$

$88-90$ II $2$

$90-92$ II $2$

$92-94$ IIIII II $7$

$94-96$ IIIII I $6$

$96-98$ IIIII II $7$

$98-100$ IIII $4$

Total $30$

Minimum humanity =$84.9$

Maximum humanity=$99.2$

Then range of data =Maximum value - Minimum value=$99.2-84.9=14.3$
