Question 1029720: Suppose the weight of cereal in a box is labeled to contain 20 oz and is distributed with mean 20.1 oz. and standard deviation .2 oz. Y is the weight of cereal in a random box.
How much do the heaviest 4% of boxes weigh?(calculate 96th percentile of distribution of Y)

Suppose that 300 samples are selected with a 95% confidence interval for the population mean. How many intervals are expected to contain the value of the population mean?

======
x = z*s + u
z = invNorm(0.96) = 1.7507
x = 1.7507*0.2 + 20.1
x = 20.45 oz

Check you text book. This question is is testing your interpretation
of the meaning of a 95% confidence interval.
