Frequency distribution of the given weekly wages of 15 workers:


Weekly wages ( in Rs)Tally marksNumber of workers
150III
200IIII
250IIII
300II
350I



(i) Minimum wages = Rs.
Maximum wage = Rs.
Therefore, Range = Maximum wage – Minimum wage
= Rs. – Rs.
= Rs.
(ii) Number of workers getting Rs. 350 = worker
(iii) Here, Minimum wages Rs.
Number of workers getting Rs. 150 = workers
Therefore, number of workers getting minimum wages = workers.
