Question 3

The number of items rejected daily by a manufacturer because of defects for the last 30 days are:
20,21,8,17,22,19,18,19,14,17,11,6,21,25,4,19,9,12,16,16,10,28,24,6,21,20,25,5,17,8
How many classes should be used in constructing a histogram?
A)6
B)5
C)7
D)4
E)8

Accepted Answer

A general rule for determining the number of classes in a histogram is to take the square root of the number of data points. In this case, there are 30 data points, so the square root is approximately 5.47. Therefore, 5 classes would be a reasonable choice. Additionally, having too many classes can make the histogram difficult to read and interpret, and having too few classes can obscure important features of the data. Therefore, B (5) is the best choice.
