The quality-assurance program for a certain adhesive formulation process involves measuring how well the adhesive sticks a piece of plastic to a glass surface. when the process is functioning correctly, the adhesive strength x is normally distributed with a mean of 200 n and a standard deviation of 10 n. each hour, you make one measurement of the adhesive strength. you are supposed to inform your supervisor if your measurement indicates that the process has strayed from its target distribution.
