Question
In the 2014-2015 academic year, many public universities in the United States raised tuition and fees due to a decrease in state subsidies. The change in the cost of tuition, a shared dormitory room, and the most popular meal plan from the 2014- 2015 academic year for a sample of 10 public universities were as follows: $1589, $593, $1223, $869, $423, $1720, $708, $1425, $922 and $308. Run the descriptive statistic measures for this data set and interpret the results for the following concepts:

Expert Solution
Step 1

First write the data in ascending Order

308  423  593  708  869  922 1223 1425 1589 1720

g)

mean= ∑xn

mean=∑ 978010

mean= 978

median =size (n+12)th observation

median = size (10+12)th observation

median =size (5.5)th observation 

median =size (5)th+0.5*(size(6-5)th observation)

median =869+0.5*(922-869

median = 895.5

data is positively skewed because mean > median
