The following data represent scores on a pop quiz in a business statistics section. Suppose the data on quiz scores will be grouped into five classes. The width of the classes for a frequency distribution or histogram is the closest to .

Taking data:

                         28 78 74 89 72

                         50 55 66 26 84

                         59 64 88 23 27

                         70 63 42 37 29

The answer is

Step-by-step explanation:

As the data is not given in the question i'm guessing the data from the question i solved before

28 78 74 89 72

50 55 66 26 84

59 64 88 23 27

70 63 42 37 29

as taking the above data,

As we know for finding the width of class:

           ≈

Note : By using the above given formula you can calculate the width of any data just by taking the maximum and minimum values of data and the number of classes the data is divided into.
