Assume that females have pulse

Assume that females have pulse rates that are normally distributed with a mean of μ=72.0 beats per minute and a standard deviation σ=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 75beats per minute. The probability is?

b. If16 adult females are randomly​ selected, find the probability that they have pulse rates with a mean less than 75 beats per minute. The probability is?

c. Why can the normal distribution be used in part​ (b), even though the sample size does not exceed​ 30?
A. Since the distribution is of sample​ means, not​ individuals, the distribution is a normal distribution for any sample size.
B. Since the mean pulse rate exceeds​ 30, the distribution of sample means is a normal distribution for any sample size.
C.Since the distribution is of​ individuals, not sample​ means, the distribution is a normal distribution for any sample size.
