Question:

The histogram given below shows the number of literate females in the age group of 10 to 40 years. Study the histogram carefully and answer the question that follow:


(i)     Write the classes, assuming that all the classes are of equal width.

(ii)    What is the class width?

(iii)   In which age group are the literate females the least?

(iv)   In which age group is the number of literate females the highest?

Hint. Number of class intervals of equal width $=6$ (given), class width $=\frac{(40-10)}{6}=5$.

Solution:

(i) Age group =10 to 40

Given all the classes are of equal width

Number of class interval of equal width = 6

Class width $=\frac{40-10}{6}=5$

Classes are 10-15,15-20,20-25,25-30,30-35,35-40

(ii) Class width $=\frac{40-10}{6}=5$

(iii)Age group with least literate females = 10-15

(iv)Age group with highest literate females = 15-20
