Use the frequency histogram to complete the following parts. (a) Determine the number of classes. (b) Estimate the greatest and least frequencies. (c) Determine the class width. (d) Describe any patterns with the data.

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.

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

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
