Solution

The correct option is B
40

The class size/width of a class interval is the difference between its upper-class limit and lower-class limit.

Class size/width of the class = Upper class limit - Lower class limit

= 90 - 50

= 40

What is the width of the class interval 50-90?

Q. The class-width of the intervals in the given grouped frequency disribution table is:

Class interval	Frequency
0-10	2
10-20	10
20-30	21
30-40	19
40-50	7
50-60	1
Total	60

If the cumulative frequency for the class interval (50-60) is 92, then find x

$\begin{matrix} Class Interval & 0 - 10 & 10 - 20 & 20 - 30 & 30 - 40 & 40 - 50 & 50 - 60 Frequency & 12 & 20 & x & 18 & 10 & 6 \end{matrix}$

Class Intervals	$30 - 40$	$40 - 50$	$50 - 60$	$60 - 70$	$70 - 80$
Frequency	$120$	?	$200$	?	$185$
Cumulative Frequency	$120$	?	?	?	$900$
