In analyzing patient admissions at a hospital, it is found that 34,190 patients were admitted in a recent year. Let the random variable x represent the number of patient admissions in one day, and assume that it has a Poisson distribution. What is the standard deviation for the values of the random variable x? What is the variance? Round to three decimal places as needed.)

We are interested in the movement of patients within a hospital. For purposes of our analysis, we consider the hospital to have three different types of rooms: general care, special care, and intensive care. Based on past data, 60% of arriving patients are initially admitted into the general care category, 30% in the special care category, and 10% in intensive care. A “general care” patient has a 55% chance of being released healthy the following day, a 30% chance of...

Valley Hospital began using standards to evaluate its Admissions Department. The standard was broken into two types of admissions as follows: Type of Admission Standard Time to Complete Admission Record 30 min. 15 min. Unscheduled Scheduled The unscheduled admission took longer because name, address, and insurance information needed to be determined and verified at the time of admission. Information was collected on scheduled admissions prior to admitting the patient, thus requiring less time in admissions. The Admissions Department employs four...

Patients admitted to the intensive care unit (ICU) and requiring mechanical ventilation can develop fatal bacterial infections. A clinical trial randomly assigned 934 patients admitted to an ICU and requiring mechanical ventilation to two groups. The control group received a standard medical treatment, whereas the antibiotics group received antibiotics prophylactically in addition to the standard treatment. The study found that 107 of the 468 patients in the control group died, compared with 69 of the 466 patients in the antibiotics...
