Question

To draw a histogram to represent the foll wing frequency distribution:

Class interval	5-10	10-15	15-25	25-45	45-75
Frequency	6	12	10	8	15

Answer 1

$\Rightarrow$ Adjusted frequency $=\frac{f}{Widthoftheclass}\times 5$

$C.I$	$f$	$Widthoftheclass$	$Adjustedfrequency$
$5-10$	$6$	$5$	$\frac{6}{5}\times 5=6$
$10-15$	$12$	$5$	$\frac{12}{5}\times =12$
$15-25$	$10$	$10$	$\frac{10}{10}\times 5=5$
$25-45$	$8$	$20$	$\frac{8}{20}\times 5=2$
$45-75$	$15$	$30$	$\frac{15}{30}\times 5=2.5$
