A cell phone manufacturer inspects the video display on each
color phone to verify that the screen can display all colors with
the brilliance their customers have come to expect. Each phone is
turned​ on, run through a​ self-test procedure, and classified as
either acceptable or unacceptable based on test performance. Based
on historical​ data, the manufacturer produces 1.9 percent
defective displays.
If they inspect​ 5,000 phones each day for the next 10​ days,

their sample mean mirrors their historical process​ average? Your
control limit should provide coverage of 99.7% of the population.
