Describe the data in terms of the basic descriptive statistics (mean,
median, and so on). Are the data normally distributed? Why or why
not?

#### 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), ...
