Assume that females have pulse rates that are normally distributed with a mean of \( \mu=75.0 \) beats per minute and a standard deviation of \( \sigma=12.5 \) 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 less than 82 beats per minute. The probability is 0.7123 . (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 less than 82 beats per minute. The probability is \( \square \). (Round to four decimal places as needed.)
