Assume that females have pulse rates that are normally distributed with a mean of u -75.0 beats per minute and a standard deviation of o - 12.5 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 68 beats per minute and 82 beats per minute. The probability is 0.4246 . (Round to four decimal places as needed.) b. If 4 adult females are randomly selected, find the probability that they have pulse rates with a mean between 68 beats per minute and 82 beats per minute. The probability is (Round to four decimal places as needed.)
