(a) What is the probability that on average, the weight of a carton is more than 9.135 oz? (b) What is the probability that on average, the weight of a carton is between 9.125 oz and 9.525 oz? (c) The specification strictly enforced for the filling machine is that all cartons need to have a mean weight of 9.0 + 0.125 oz. If any carton is produced with weight outside these bounds, it is considered by the supplier to be defective. Calculate the probability that a carton selected is considered defective.

(a)
What is the probability that on average, the weight of a carton is more than 9.135 oz?
(b)
What is the probability that on average, the weight of a carton is between 9.125 oz and
9.525 oz?
(c)
The specification strictly enforced for the filling machine is that all cartons need to have
a mean weight of 9.0 + 0.125 oz. If any carton is produced with weight outside these
bounds, it is considered by the supplier to be defective. Calculate the probability that a
carton selected is considered defective.
