There are 1 squares in 0-10

There are 2 squares in 10-20

There are 2 squares in 20-30

Answer 2

The histogram for the data is attached below.

Explanation:

The data for the number of houses Gregg the garbage man visited each day last week is as follows:

S = {12, 28, 33, 37, 23, 14, 9​}

In this case we need to create a histogram for the provided data.

According to the graph provided we know that the class intervals are:

CI = 0 - 10, 10 - 20, 20 - 30, 30 - 40

The frequency distribution table is as follows:

Class Interval Frequency

0 - 10 1

10 - 20 2

20 - 30 2

30 - 40 2

The histogram for the data is attached below.
