Hold, please! ~ Ask A Nurse is a service provided to subscribers of a large health insurance company where customers can call a toll-free number and ask a nurse about non-urgent health problems. The company has set a goal that customers wait no more than 3.5 minutes on hold to speak to a nurse. In order to manage staff hours and availability, they want to set up a quality control process. They will assume that wait

Hold, please! - Ask A Nurse is a service
provided to subscribers of a large health
insurance company where customers can
call a toll-free number and ask a nurse about
non-urgent health problems. The company
has set a goal that customers wait no more
than 3.5 minutes on hold to speak to a
nurse. In order to manage staff hours and
availability, they want to set up a quality
control process. They will assume that wait
times are normally distributed with a
standard deviation of 1.7 minutes and take a
random sample of 3 calls every shift. If the
mean wait time for a shift is more than 4
minutes, they will reallocate resources to try
to bring the wait time down.
