### Statistical Analysis of Charity Care in Hospitals

**Problem Statement:**
What percentage of hospitals provide at least some charity care? Based on a random sample of hospital reports from eastern states, the following information is obtained (units in percentage of hospitals providing at least some charity care):

\[ 57.5, 55.5, 53.5, 65.7, 59.0, 64.7, 70.1, 64.7, 53.5, 78.2 \]

**Instructions:**

1. **Objective:**
- Calculate the mean and standard deviation of the sample data.
- Determine a 90% confidence interval for the population percentage of hospitals providing at least some charity care.

2. **Steps:**

(a) **Calculate Mean and Standard Deviation:**

- Use a calculator with mean and sample standard deviation functions to find:
- Mean percentage ($\overline{x}$)
- Sample standard deviation ($s$)

(Round your answers to four decimal places.)

**Input Fields:**
- $\overline{x} =$ _____ %
- $s =$ _____ %

(b) **Determine the 90% Confidence Interval:**

- Calculate the 90% confidence interval for the population average ($\mu$) of the percentage of hospitals providing at least some charity care.

(Round your answers to one decimal place.)

**Input Fields:**
- Lower limit: _____ %
- Upper limit: _____ %

**Tool Used:**
- **SALT Calculator:** A tool to assist in statistical calculations, ensuring more accurate and efficient data analysis.

This exercise will guide learners in performing statistical analyses using real-world data, building skills in calculating descriptive statistics and constructing confidence intervals.
