If the class creates a histogram of the data in the table, there would be 8 students in the range 12 cm to 13.9 cm

What is an histogram?

An histogram is used to display the frequency of data elements such that the length of the bars represents the frequency

The dataset is represented as:

• 14.0, 11.5, 12.1, 16.2, 13.5, 14.3, 16.8.
• 12.4, 13.7, 12., 14.7, 15.2, 11.9, 15.6.
• 13.8, 14.2, 12.5, 15.0, 16.0, 13.1, 11.7.

The data elements from 12 cm to 13.9 cm are

12.1, 13.5, 12.4, 13.7, 12, 13.8, 12.5, 13.1

Count the number of elements above

Count = 8

Hence, there are 8 elements in the range 12 cm to 13.9
