Mrs. Ferguson, your school librarian, asks you to conduct a survey of how many books students read during the year. You get the following results: $12, 24, 10, 36, 12, 21, 35, 10, 8, 12, 15, 20, 18, 25, 21$, and $9$.

1. Use the data to create a stem-and-leaf plot.

   Answer (a):

   $0$	$8\ \ 9$
   $1$	$0\ \ 0\ \ 2\ \ 2\ \ 2\ \ 5\ \ 8$
   $2$	$0\ \ 1\ \ 1\ \ 4\ \ 5$
   $3$	$5\ \ 6$

2. Calculate the mean, median, and mode for the data.

   Hint (b):

   Refer to the example from the Math Notes box from Lesson 1.3.3 for help.
