**Title: Understanding Confidence Intervals in Healthcare Statistics****Introduction:**In assessing the percentage of hospitals that provide at least some charity care, statistical data from a random sample of hospital reports from eastern states is utilized. The following percentages represent hospitals providing some level of charity care:**Data:** 57.3, 55.5, 53.3, 65.5, 59.0, 64.7, 70.1, 64.7, 53.5, 78.2**Assumption:** The data distribution is approximately normal, allowing for standard statistical computations.**Tasks:****(a) Calculate the Sample Mean and Standard Deviation**To determine the average percentage of hospitals that offer charity care and understand the variability within the data, use a calculator to compute:- **Sample Mean ($\bar{x}$)**: This provides the average percentage.- **Sample Standard Deviation ($s$)**: This indicates the amount of variation from the mean.**(b) Determine the 90% Confidence Interval**Establish a range in which the true population mean is likely to fall, with a confidence level of 90%. This involves calculating:- **Lower Limit**: The lower boundary of the confidence interval.- **Upper Limit**: The upper boundary of the confidence interval.**Conclusion:**These calculations provide insights into the typical extent of charity care offerings among hospitals in the studied region, aiding in healthcare policy and planning. Understanding these statistics is vital for grasping how charity care is distributed and identifying areas for potential improvement.*Note: Round all answers to one decimal place for uniformity and ease of interpretation.*

Choose the appropriate statistical test. When computing, be sure to round each answer as indicated. A dentist wonders if depression affects ratings of tooth pain. In the general population, using a scale of 1-10 with higher values indicating more pain, the average pain rating for patients with toothaches is 6.8.
