Please answer it fast, I need it tonight.
At QT Sugar factory the amounts which go into bag of sugar are supposed to be normally
distributed with mean 36 kg and standard deviation 0.1 kg. Once every 30 minutes a bag is
selected from the production line, and its contents are noted precisely. If the amount of the bag
goes below 35.8 kg or above 36.2 kg, then the bag will be declared out of control.
a) If the process is in control, meaning µ = 36 kg and = 0.1 kg, find the probability that the bag will be declared out of control.
b) In the situation of (a), find the probability that the number of bag found out of control in an
eight-hour day (16 inspections) will be zero.
c) In the situation of (a), find the probability that the number of bag found out control in an eight hour day (16 inspections) will be exactly one.
d) If the process shifts so that µ =37 kg and =0.4 kg find the probability that a bag will be
declared out of control.
