Question

If we draw a histogram for the class interval 15 - 30, what will be the value of 'a' ?

• A. 3
• B. 11
• C. 4
• D. 7

Answer 1

The correct option is D 7

Comparing the table and the graph we can pbserve

c= 15

d = 30

When a frequency distribution table is depicted using histograms,

the number of tally marks of a class interval is represented using the height of bars in the histogram.

Here, when the class interval 15 - 30 is depicted in a histogram since the tally marks are 7,

the value of a = 7,

as the height of the bar is 7.
