Refer to the accompanying data set and use the 25 home voltage measurements to construct a frequency distribution with five classes. Begin with a lower class limit of 122.9 volts, and use a class width of 0.2 volt. Does the result appear to have a normal distribution? Why or why not?

A frequency distribution table is a table that summarizes data in two columns.

The result does not appear to have a normal distribution.

How to construct the frequency distribution table

From the dataset, we have the following classes using 5 classes with a lower class limit of 119.4 and a class width of 0.2 volts

119.4 - 119.6, 119.7 - 119.9, 120.0 - 120.2. 120.3 - 120.5. and 120.6 - 120.8

So, the frequency distribution table is:

Class                   Frequency

119.4 - 119.6             4

119.7 - 119.9            10

120.0 - 120.2          6

120.3 - 120.5         5

120.6 - 120.8         0

The result does not appear to be normal.

This is so, because the frequency table do not go in form of a bell shape
