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?

The histogram for the above given frequency table is:

(i) The group earning Rs. 830-840 per week has the maximum number of workers

(ii) The workers who earn more than Rs 850 fall under the group of 850-860 or 860-870 or 870-880 or 880-890.

Therefore, there are total 10 workers who are earning Rs. 850 or more.

(iii) The workers who earn less than Rs 850 fall under the group of 800-810 or 810-820 or 820-830 or 830-840 or 840-850. Therefore, there are total20 workers who are earning less than Rs. 850.
