The distribution of the tuitions, fees, and room and board charges of a random sample of public 4-year degree-granting postsecondary institutions is shown in the pie chart. Make a frequency distribution for the data. Then use the table to estimate the sample mean and the sample standard deviation of the data set. Use $26249.50 as the midpoint for "$25,000 or more." Complete the frequency distribution for the data. (Type integers or decimals. Do not round.)
