To find the number of people who are 40 or younger with no opinion, we can look at the groups in the age ranges provided: 21–30 and 31–40.
From the table:
- For the age group 21–30, the number of people with no opinion is 18.
- For the age group 31–40, the number of people with no opinion is 25.
Now, we can sum these two amounts:
18 (21–30) + 25 (31–40) = 43
So, the total number of people who are 40 or younger with no opinion is 43.
The correct response is 43.
