Question

1) Assume that females have pulse rates that are normally distributed with a mean of mu equals 73.0μ beats per minute and a standard deviation of sigma equals 12.5σ beats per minute. Complete parts​ (a) through​ (c) below.

a. If 1 adult female is randomly​ selected, find the probability that her pulse rate is less than 80 beats per minute.The probability is 0.71230

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.The probability is _____

2) Assume that females have pulse rates that are normally distributed with a mean of mu equals 73.0μ beats per minute and a standard deviation of sigma equals 12.5σ beats per minute. Complete parts​ (a) through​ (c) below.

a. If 1 adult female is randomly​ selected, find the probability that her pulse rate is between 69 beats per minute and 77 beats per minute.The probability is 0.2510

​(Round to four decimal places as​ needed.)
