4-70.

Over winter vacation, Serena's class was assigned to read at least $200$ pages of a book. When school started again, she asked her teammates and the next closest team how many pages each of them had read. The answers were: $220, 312, 250, 483, 200, 0, 275$, and $495$.

1. Calculate the mean, median, and mode for the number of pages read.

Creating a stem-and-leaf plot for this problem would be helpful.

2. If the person who did not do the assignment is not counted, how do the measures of central tendency change?

Re-calculate the measures of central tendency leaving out the $0$. Which one changes the most?
