Comparing Hospital Quality to Mortality Rates

Let's say you're a consultant who is on a team analyzing the performance of hospitals. You are given data on hospitals' mortality rates and their safety performance. Specifically, these data include hospitals around the United States in 2017; mortality corresponds to patients' death rates of heart failure within 30 days after entering the hospital, and the hospital's overall safety performance rating (on a scale from 0 to 100).
