  A histogram titled "Membership (in thousands)" has a horizontal axis labeled with five intervals and a vertical axis labeled from 0 to 20 in increments of 1. There are vertical bars of equal width, each of which is over a horizontal axis label. The heights of the bars are as follows, where the horizontal axis label is listed first and the height is listed second: 16-24, 2; 25-33, 4; 34-42, 7; 43-51, 14; 52-60, 16.

Answer 1

To find the number of members who are 33 years of age and under, we need to look at the given intervals that fall under or equal to 33 years of age. The relevant intervals based on the histogram data are:

- **16-24**: Height = 2 (this represents 2,000 members)
- **25-33**: Height = 4 (this represents 4,000 members)

Now we can sum the heights of these two bars to get the total number of members aged 33 and under:

\[
\text{Total members aged 33 and under} = 2 + 4 = 6 \text{ (thousands)}
\]

Since we need to give the answer in terms of actual members (not in thousands):

\[
6 \text{ (thousands)} = 6,000 \text{ members}
\]

Thus, the Toy Train Collectors' Club has **6,000 members 33 years old and younger**.
