There is a severe shortage of critical care doctors and nurses to provide intensive-care services in hospitals. To offset this shortage, many hospitals are using electronic intensive-care units (eICUs) to help provide this care to patients. eICUS use electronic monitoring tools and two-way communication through video and audio so that a centralized staff of specially trained doctors and nurses-who can be located as far away as Australia-can provide critical care services to patients located in remote hospitals without fully staffed ICUs. One of the most important metrics tracked by these eICUS is the time that a patient must wait for the first video interaction between the patient and the eICU staff. Suppose the following is a sample of 40 patient waiting times until their first video interaction with the eICU staff. Wait Time (minutes) 39 45 48 48 43 43 44 44 37 50 41 45 40 45 40 44 48 40 40 47 41 48 39 41 42 42 41 40 40 54 42 41 39 41 39 48 42 43 44 60 60 36 39 36 38 36 38 42 42 (a) Compute the mean waiting time (in minutes) for these 40 patients. (Round your answer to two decimal places.) min (b) Compute the median waiting time (in minutes). min (c) Compute the mode (in minutes). min (d) Compute the first and third quartiles (in minutes).
