Answer 2

Answer:

The total number of volunteers working more than 15 hours are 60.

Step-by-step explanation:

From the histogram, we see that,

The range of volunteers working more than 15 hours are given by,

When the number of hours worked are between 16-20 and 21-25.

So, the number corresponding to these ranges will given the number of volunteers working more than 15 hours.

Thus, we have,

The number of volunteers working between 16-20 hours are 50.

The number of volunteers working between 21-25 hours are 10.

Hence, the total number of volunteers working more than 15 hours = 50+10 = 60.
