### 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.
