Answer
Explanation:
Step1: Understand stem - and - leaf plot
In a stem - and - leaf plot, the stem represents the tens digit and the leaf represents the units digit.
Step2: Identify scores more than 20
For scores more than 20, we consider stems of 2 and 3. When the stem is 2, the leaves are 1, 4, 4, 7, 8 (5 values). When the stem is 3, the leaves are 0, 5 (2 values).
Step3: Calculate total number
Add the number of values for stem 2 and stem 3. $5 + 2=7$.
Answer:
7
