The numbers of the 2013 tuitions (in dollars) of 10 randomly selected 2 year, public colleges are

1772,1752,3485,1138,2328,1854,3598,3722,4680,3030.

The mean of a set of observations is their sum divided by the number of observations, e.g. The mean x of n observation x1,x2...,xn is given by: PSKn x=1/n(x1+x2+...+xn)=1/n*Σxi i=1ZSK

From the above definition we have mean tuition is

PSKx=1/10(1772+1752+3485+1138+2328+1854+3598+3722+4680+3030) =27359/10=2735.9ZSK

Therefore, the mean tuition is 2735.9
