Question

Represent the following distribution of ages (in years) of 35 teachers in a school by means of a histogram:

Age (in years)	25 – 30	30 – 35	35 – 40	40 – 45	45 – 50
Number of teachers	12	11	8	1	3

Answer 1

Here is the histogram representing the age distribution of 35 teachers in a school.

The age group 25 – 30 has the highest number of teachers (12). 

The number decreases in older age groups, with the 40 – 45 group having the fewest (1).

This graph clearly shows the frequency distribution of teachers’ ages using equal class intervals.
