Assume that females have pulse rates that are normally distributed with a mean of p = 73.0 beats per minute and a standard deviation of o = 12.5 beats per minute. Complete parts (a) through (0) below. E) 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.) b. If 25 adult females are randomly selected, find the probability that they have pulse rates with a mean between 69 beats per minute and 77 beats per minute. The probability is .. (Round to four decimal places as needed.)
