Clinicians at 1|-.I"'v'H have been complaining about the turnaround time for blood work. The laboratory manager decides to investigate the problem and collects turnaround time data on ve randomly selected requests every day for one month {shown in the chart below}.

Construct an X-bar chart using the standard deviation of the observations to estimate the population standard deviation. Construct an vaar chart and rvchar't using the range to calculate the control limits. b. Is the process in control? Explain. c. If the clinicians feel that any time over 1133 minutes is unacceptable, what are the CD and Cpk of this process? d. What are the next steps for the laboratory manager
