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?

(i) 830: Maximum number of workers (ii) Workers earn more than Rs 850: It will be workers who fall in the group of 850, 860, 870, 880 ∴ Sum of number of all workers = 1 + 3 + 1 + 1 + 4 = 10 (iii) The worker who earn less than Rs 850: Category will be: 800, 810, 820, 830 and 840 ∴ Sum of numbers of these workers = 3 + 2 + 1 + 9 + 5 = 20
