Books issued per day at a Udaipur library over 60 days, with deliberately unequal class widths: 0-5: 14, 5-10: 16, 10-20: 18, 20-50: 12. Find the mean number of books issued per day.

Question

Accepted Answer

14.08. Class marks are still l + u/2 : 2.5, 7.5, 15, 35. f_i x_i = 35 + 120 + 270 + 420 = 845 and f_i = 60 , so the mean is 845/60 = 14.08 books. "9.83" assumes all widths are 5 and uses the marks 2.5, 7.5, 12.5, 17.5; "8.33" uses the lower limits as x_i ; "211.25" divides by 4, the number of classes.
