### Tuition and Fees Distribution at Public 4-Year Postsecondary Institutions

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 below. The pie chart details the frequency of institutions within specified ranges of total costs. Using this data, we will create a frequency distribution and calculate the sample mean and sample standard deviation.

#### Frequency Distribution

Complete the frequency distribution for the data as follows (type integers or decimals; do not round):

| Class                  |    x      |  f  |
|------------------------|-----------|-----|
| $15,000 – $17,499      | 16249.5   | 10  |
| $17,500 – $19,999      | 18749.5   |  9  |
| $20,000 – $22,499      | 21249.5   | 13  |
| $22,500 – $24,999      | 23749.5   | 12  |
| $25,000 or more        | 26249.5   |  5  |

#### Calculations
- **Sample Mean**

The sample mean \(\bar{x}\) is calculated as follows:

\[
\bar{x} = \$20892.36 \text{ (rounded to the nearest cent)}
\]

- **Sample Standard Deviation**
  
The sample standard deviation \(s\) calculation is yet to be completed and will be shown here once computed. (Round to the nearest cent).

#### Explanation of Pie Chart
The provided pie chart visually represents the relative frequencies of the different cost classes.

- The largest segment (green, 27.1%) represents the $20,000 - $22,499 class with 13 institutions.
- The yellow segment (25.0%) represents the $22,500 - $24,999 class with 12 institutions.
- The blue segment (20.8%) represents the $15,000 - $17,499 class with 10 institutions.
- The red segment (18.8%) represents the $17,500 - $19,999 class with 9 institutions.
- The purple segment (8.3%) represents $25,000 or more with 5 institutions.

This visual tool helps quickly understand the proportion of institutions falling within each cost range.
