The time from when a patient is discharged from North Shore Hospital to the time the discharged patients bed is ready to be assigned to a new patient is referred to as the bed assignment turnaround time. If the bed turnaround time (measured in minutes) is excessive, it can cause problems with patient flow and delay medical procedures throughout the hospital. This can cause long waiting times for physicians and patients, thus creating customer dissatisfaction. The admissions has assigned a patient care associate to measure the bed turnaround time for a randomly selected bed each morning, afternoon, and evening for 30 days. Further a team of experts create mean chart and S chart by considering the Z=3. These charts are given below. Now calculate/identify the following:

a. What is the mean and standard deviation of bed turnaround time? [0.5 Marks + 0.5 Marks]

b. What is the value of UCL and LCL for both the charts? Is the process is in control? [2 Marks +1 Marks]

c. Is the hospital capable of consistently achieving bed turnaround times of 120 minutes 10 minutes without improving the process? [4 Marks]
