Answer: See the attached image below for the dot plot
==============================================
Explanation:
The list
{50, 45, 24, 28, 27, 38, 21, 22, 23, 42, 41, 35, 37, 25, 43}
sorts to
{21, 22, 23, 24, 25, 27, 28, 35, 37, 38, 41, 42, 43, 45, 50}
Draw out a number line. Make sure to go as far down to 21 and as high as 50.
Then plot dots above the numbers 21, 22, 23,24,25,27,28, etc. Each item in the sorted list will get a dot overhead. In this case, there are no repeated items, so each stack is 1 dot high.
See the diagram below.
