Assume that females have pulse rates that are normally distributed with a mean of 73 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 less than 77 beats per minute The probability is 0 6255 Round to four decimal places as needed b If 16 adult females are randomly selected find the probability that they have pulse rates with a mean less than 77 beats per minute The probability is Round to four decimal places as needed
