Assume that females have pulse rates that are normally distributed
with a mean of 75.0 beats per minute and a standard deviation of
12.5 beats per minute.
A. If 1 adult female is randomly selected, find the
probability that her pulse rate is less than 81 beats per
minute.
B. If 25 adult females are randomly selected, find probability
that they have pulse rates with a mean less than 81 beats per
minute.
