Data was collected for 253 randomly selected 10 minute intervals. For each ten-minute interval, the number of people entering the atrium of a large mall were recorded. The data is summarized in the histogram below. 20 40 60 80 Number of People in 10 min 180 200 220 240 260 280 Frequency What is the class width for this histogram (and corresponding GFDT)

The class width of a histogram is simply the width of the bar of the histogram. The class width of the histogram is 10.

I've added as an attachment, the histogram of the distribution.

The width is the difference between the beginning of a bar and the beginning of the next bar.

From the attached figure, we have:

So, the class width is:

Hence, the class width of the histogram is 10.

20

Step-by-step explanation:

Step 1

The Class Width is the difference between the lower limits of each class width.

Step 2.

The Graph is not shown but from the write-up, the values in the X axis are listed above as 180 200 220 240 260 280 as the Number of People in 10 min.

Step 3

Subtracting the lower limits then would be,

200-180 = 20

220-200 = 20

240-220= 20

260 - 240 = 20

280 - 260 = 20

The class widths are uniform at 20. 20 is the Class Width for this Histogram

to rewrite a literal equation you may need to divide by a number, or by a variable.
