A key hospital outcome measure of clinical performance is length of stay (LOS), that is, the number of days a patient is hospitalized. For patients at one hospital with past four years has consistently decreased. The hospital also has data for various treatment options such as the percentage of patients who received aspirin upon arri (LVSD). The data are as follows: Year Average LOS Aspirin on arrival LVSD medication 2007 4.33 days 95% 2008 4.34 days 98% 2009 4.12 days 98% 2010 4.29 days 100% Calculate descriptive statistics for the data. Do not round intermediate calculations. Round your answers to four decimal places, when needed. Descriptive Statistics: LOS, Aspirin, LVSD Aspirin LVSD Mean Standard Error Wariable LOS (days) spirin (%) LVSD (96) Calculate correlations for the data. Do not round intermediate calculations. Use a minus sign for negative values, if any. Round your answers to three decimal places. Correlations: LOS, Aspirin, LVSD LOS Aspirin 89% 94% 97% 98% Standard Deviation Minimum Median Maximum

Question
A key hospital outcome measure of clinical performance is length of stay (LOS), that is, the number of days a patient is hospitalized. For patients at one hospital with acute myocardial infarction (heart attack), the length of stay over the past four years has consistently decreased. The hospital also has data for various treatment options such as the percentage of patients who received aspirin upon arrival and cardiac medication for Left Ventricular Systolic Dysfunction (LVSD). The data are as follows: Year Average LOS Aspirin on arrival LVSD medication 2007 4.33 days 89% 2008 4.34 days 94% 2009 4.12 days 97% 2010 4.29 days 98% Calculate descriptive statistics for the data. Do not round intermediate calculations. Round your answers to four decimal places, when needed. Descriptive Statistics: LOS, Aspirin, LVSD Variable LOS (days) Aspirin (%) LVSD (%) Minimum TODO Calculate correlations for the data. Do not round intermediate calculations. Use a minus sign for negative values, if any. Round your answers to three decimal places. Aspirin 95% 98% 98% 100% Mean LVSD Correlations: LOS, Aspirin, LVSD LOS Ⓡ X * Standard Error Aspirin Standard * Deviation Median Maximum
