The ages of people in attendance of a local group function are shown in the histogram below.
which of the following statements correctly describes the data?
a. sixteen of the attendees were over the age of 50.
b. there were a total of 50 people in attendance.
c. five less attendees were older than 40 than those 40 or younger.
d. more than half of the attendees were between the ages of 21 and 50.

Let's look at all the options:

A.Sixteen of the attendees were over the age of 50.
it was 6 until 60 years, then 3 until 70, 4 until 80, 1 until 90 ad 2 until 100: together 16, yes, correct answer!!

B. There were a total of 50 people in attendance.
Let's add up (from left to right): 8+5+10 (23 so far)+7+9 (39 so far-until 50) and then 16 that's 55 total: false:

C. Five less attendees were older than 40 than those 40 or younger.

False! there were 8 attendees under 10 and 16 over 50!

D.More than half of the attendees were between the ages of 21 and 50.
Between 21 and 50 there were 10+7+9=26, which is less than half of 55 - false!
