The amount of water in a bottle is approximately normally
distributed with a mean of 2.85 litres with a standard deviation of
0.035-liter.
b. If a sample of 4 bottles is selected, the probability that
the sample mean amount contained is less than 2.82 litres is
0.043.
c. If a sample of 25 bottles is selected, the probability that
the sample mean amount contained is less than 2.82 litres is
0.

A soft drink machine is regulated so that the amount of drink
dispensed is approximately normally distributed with a standard
deviation equal to 1.5 deciliters. Find the 95% confidence interval
for the mean of all soft drinks dispensed by this machine if a
random sample of 36 drinks had an average content of 22.5
deciliters. What statistical table to be used? What is the tabular
value? What is the computed lower confidence limit? What is the
computed upper confidence limit?

A class consisting of 10 students takes a test. The scores are
approximately normally distributed with a mean of 74 and a standard
deviation of 11. The teacher wants to curve the grades in the
following manner: the top 5% get As, the next highest 12% get Bs,
the bottom 5% get Fs, and the next lowest 12% get Ds. The rest will
get Cs. Find the Z-scores for each line and the test score
corresponding to each z score
