To determine the percentage of patients who were hospitalized past their anticipated discharge date, Keesha can use the formula she remembers: Percentage = (Number of times something happened / Number of times something could have happened) * 100 In this case, the number of times something happened is 30 (patients hospitalized past their anticipated discharge date), and the number of times something could have happened is 500 (total discharges). Therefore, the calculation would be: Percentage = (30 / 500) * 100 Percentage = 6% Therefore, the percentage of patients who were hospitalized past their anticipated discharge date is 6%. If Keesha had not remembered the basic formula, she could have used the following strategies to find out how to calculate the statistics for her manager: 1. Consulting textbooks or online resources: There are numerous textbooks and online resources available that provide explanations and formulas for various statistical calculations. Keesha could have referred to these resources to find the formula she needed. 2. Seeking help from colleagues or mentors: Keesha could have reached out to her colleagues or mentors who have expertise in statistics or data analysis. They could have provided guidance and shared the formula with her. 3. Attending training
