A nationwide random sample of university professors revealed that
24 professors consumed a total of 6,548 mg of caffeine daily, with
a standard deviation of 48 mg. Assuming that the amount of caffeine
consumed per person per day is normally distributed, is there
sufficient evidence to conclude that the average amount of caffeine
consumed per day by university professors is more than 250 mg using
α = 0.05?

A simple random sample of 48 adults is obtained from a normally
distributed population, and each person's red blood cell count
(in cells per microliter) is measured. The sample mean is 5.19 and
the sample standard deviation is 0.53. Use a 0.01 significance
level and the given calculator display to test the claim that the
sample is from a population with a mean less than 5.4, which is a
