Solution Preview

The sum of all the student expenditures in all the 30 states=$228,031.53
The mean(average) for all the expenditures is 7.601.051 or $7,601.05 per student expenditure
(you must round to make a dollar amount.)

Mean= (Sum of expenditures/30)

To gather the median first make sure the data is in order from least to greatest.
If there is not a "middle" number in the center, take the 2 middle numbers and find their mean/average.

Data from least to greatest: $5571.30(UT), $5669.75(MS), ...
