Question

assume that females have pulse rates that are normally distributed
with a mean of 73.0 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 76 bpm

b. if 25 adult females are randomly selected, find the
probability that they have pulse rates with a mean less than 76
bpm.

c. why can the normal distribution be used in part b, even
though the sample size does not rxceed 30?
