A shopkeeper in Jaipur noted the daily sales (in Rs thousands) for 30 days. The smallest value is 14 and the largest is 59. He wants exactly 5 equal class intervals to cover all the data. What class size should he choose so that 5 classes neatly cover the range?

Question

Accepted Answer

10. Range = 59 - 14 = 45. For 5 classes, size must be at least 45/5 = 9, but a convenient size of 10 gives classes 10-20, 20-30, 30-40, 40-50, 50-60, which cover 14 to 59 in 5 classes.
