B. Which measures best represents the data? Use the results to support your answer.
C. What is the outlier and how does it affect the data?

1 answer

Mean = (15000x3+20000x4...)/(3+4+5+2+1)
= 22.33333
Median = 23000

Outlier would depend on what how you define it, but it would probably be 45000 and it'd affect the mean and standard deviation of the plot.
