Question

Draw a histogram for the frequency table made for the data in Question 3 and answer the following questions. (i) Which group has the maximum number of workers? (ii) How many workers earn $Rs.850$and more? (iii) How many workers earn less than $Rs.850$ ?

Answer 1

(i) $830-840$ is the group having maximum number of workers, $9$, compared to other groups.

On observing the graph we note that group having weekly wage $830-840$ there are $9$ workers working.

(ii) Workers earning $Rs.850$and more$=1+3+1+1+4=10$

$20$ workers earn less than $Rs.850$

On observing the graph we note that group having weekly wage less than $Rs.850$, there are $20$ workers working when we add all the workers having wage less than $Rs.850$.

(iii) Workers earning less than $₹850=3+2+1+9+5=20$

On observing the graph we note that group having weekly wage less than $Rs.850$, there are $20$ workers working when we add all the workers having wage less than $Rs.850$.
