Assume that females have pulse rates that are normally distributed
with a mean of 74 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 80 beats per
minute.
(b) if 16 adult females are randomly selected, find the
probability that they have pulse rates with a mean less than 80
beats per minute
(2a) if 1 adult female is randomly selected find the
probability that her pulse rate is greater than 70 beats per
minute.
(b) if 25 adult females are randomly selected, find the
probability that they have pulse rates with a mean greater than 70
beats per minute.
(3a) if 1 adult female is randomly selected, find the
probability that her pulse rate is between 72 beats per minute and
76 beats per minute.
(b) If 4 adult females are randomly selected, find the
probability that they have pulse rates with a mean between 72 beats
per minute and 76 beats per minute.
