Answer 1

Answer:

16 and 73

Step-by-step explanation:

The question is missing some data. The distribution of the number of students is represented on the following stem-and-leaf plot:

$\begin{array}{cc}1&69\\2&445\\3&347\\4&0269\\5&\\6&\\7&3\\8&\\9&\end{array}$

The numbers in the first column represent the tens and the numbers on the second column represent the units. The number of students over the past 13 years were:

16, 19, 24, 24, 25, 33, 34, 37, 40, 42, 46, 49, 73.

Therefore, the smallest and largest number of students were 16 and 73.
