is question: 3 Submit test point(s) possible Assume that females have pulse rates that are norrnall y distributed with a mean of p = 76.0 beats per minute and a standard deviation of cr = 12.5 beats per minute. Compiete parts (a) through (c) below. a. If 1 adult female is randomty selected. nd the probability that her pulse rate is less than 83 beats per minute. The probability is D\\ {Round to four declmaiiplaoes as needed.) is. If 25 adult females are randomly selected. nd the probability that they have pulse rates with a mean less than 83 beats per minute. The probability is I]. . (Round to four decimal pieces as needed.) . l c. Why can the normal distribution be used in part (b), even though the sample size does not exceed 30? . Since the distribution is of individuals. not sample means. the distribution is a normal distribution for any sample size. . Since the distribution is of sample means. not individuals, the distribution is a normal distribution for any sample size. . Since the original population has a normal distribution, the distribution of sample means is a normal distribution for any sample size. . Since the mean pulse rate exceeds 30, the distribution of sample means is a normal distribution for any sample size
