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 varlous 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: Caiculate descriptive statistics for the data. Do not round intermediate calculations. Round your answers to four decimal places, when needed. Descriptive Statistics; LOS, Aspirin. LVSD Calculate correlations for the data. Do not round intermediate calculations. Use a minus sign for negative values, if any. Round your answers to three decimat places. Choose the correct'graph showing the LOS as a function of the Aspirin on arrival. The correct graph is B. Scatterplot of LOS vs Aspirin c. Scatterplot of LOS vs Aspirin D. Scatterplot of LOS vs Aspirin Choose the correct graph showing the LOS as a function of the LVSD. The correct graph is B; Scatterplot of LOS vS LVSD c Scatterplot of LOS vS LVSD D. Scatterplot of LOS vs LVSD
