Answer:

Following are the solution to this question:

Step-by-step explanation:

Please find the complete question in the attachment file.

In choice (a):

7 classes are available because there are 7 bars of the histogram.

In choice (b):

Its lowest frequency is $32,000 for employee wages

There are around 20 of them.

It is around 20 the least frequency

$ 47,000 was its largest frequency for employees.

There are another 300

The highest frequency is about 300

In choice (c):

Its width of the class is 5, its difference between all the centers, that can also be seen.

In choice (d):

They get below in when we see frequencies per each class.

\text{Class Midpoint} \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \  \text{Frequency}\\\\32  \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \  20\\\\37 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \  180\\\\42  \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \  270\\\\47 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \  300\\\\52 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \  250\\\\57 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \  70\\\\62 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \  60\\\\

They can see in this certain half of workers' wages are between 40,000 and 49,000 dollars.
