The time from when a patient is discharged from ABC Hospital to the time the discharged patient's bed is ready to be assigned to a new patient is referred to as the bed assignment tumaround time. If the bed tumaround time 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 tumaround time for a randomly selected bed each morning, aftemoon and evening for 30 days. Following are the bed turnaround time sample observations: Please construct X-chart with Z. standard deviation is 0.08 then give your comments in order to improve quality.
