Answer 1

We are given a data set in the form of a stem and leaf plot. This means that in the stem column we have the decimal digit and in the leaf column we have the units digits.

We are asked for the number of students that have scored at least 17, this means the number of students with a score that is greater or equal to 17. From the graph those scores are:

`17,18,19,19,20,20,20,20`

There are 8 students that scored at least 17.
