Anx chart with three$-$sigma limits has parameters as follows:

$6.$

UCL $=104$ Center line $=100$ LCL $=96$ n$=5$

$6\mathrm{.}3$

Suppose the process quality characteristic being con$-$ trolled is normally distributed with a true mean of $98$ and a standard deviation of $8.$ What is the probability that the control chart would exhibit lack of control by

at least the third point plotted
