A process has mean $12$ and standard deviation $3\mathrm{.}0.$ The process is monitored by taking samples of size $5$ at regular intervals. The process is declared to be out of control if a point plots outside the $3\backslash$sigma control limits on a chart. If the process mean shifts to $14,$ what is the average number of samples that will be drawn before the shift is detected on a
