Question

1) The histogram displays the number of years of service for a sample of U.S. Navy veterans.

a) How many veterans in the sample had more than 15 years of service?

b) How many veterans are represented by the histogram?

Answer 1

A.) I would say twelve because all you have to do is add from 11-15 all the way to 21-25 and it would give you 12
B.) I would say 48 because you have to add all off the numbers together and you will get 48...

Answer 2

To find the answer to question A, you must look at all of the sections to the right of fifteen on the histogram's x-axis and add the totals.

4+2 = 6

So, 6 veterans had more than 15 years of service.

For question B, you must add all of the data, in each bar, together.

25 +12 + 7 + 4 + 2 = 50

So, 50 veterans are represented by the histogram.
