Answer f please

Suppose the lengths of the pregnancies of a certain animal are approximately normally distributed with mean μ = 195 days and standard deviation o=18 days. Complete parts (a) through (f) below.

(Round to four decimal places as needed.)
(c) What is the probability that a random sample of 18 pregnancies has a mean gestation period of 188 days or less?
The probability that the mean of a random sample of 18 pregnancies is less than 188 days is approximately 0.0495. (Round to four decimal places as needed.)
Interpret this probability. Select the correct choice below and fill in the answer box within your choice.
(Round to the nearest integer as needed.)
O A. If 100 independent random samples of size n=18 pregnancies were obtained from this population, we would expect
OB. If 100 independent random samples of size n=18 pregnancies were obtained from this population, we would expect
sample(s) to have a sample mean of exactly 188 days.
sample(s) to have a sample mean of 188 days or more.
C. If 100 independent random samples of size n=18 pregnancies were obtained from this population, we would expect 5 sample(s) to have a sample mean of 188 days or less.
(d) What is the probability that a random sample of 33 pregnancies has a mean gestation period of 188 days or less?
The probability that the mean of a random sample of 33 pregnancies is less than 188 days is approximately 0.0127. (Round to four decimal places as needed.)
Interpret this probability. Select the correct choice below and fill in the answer box within your choice.
(Round to the nearest integer as needed.)
O A. If 100 independent random samples of size n = 33 pregnancies were obtained from this population, we would expect
B. If 100 independent random samples of size n=33 pregnancies were obtained from this population, we would expect 1
OC. If 100 independent random samples of size n = 33 pregnancies were obtained from this population, we would expect
(e) What might you conclude if a random sample of 33 pregnancies resulted in a mean gestation period of 188 days or less?
This result would be unusual, so the sample likely came from a population whose mean gestation period is less than 195 days.
(f) What is the probability a random sample of size 18 will have mean gestation period within 12 days of the mean?
The probability that a random sample of size 18 will have a mean gestation period within 12 days of the mean is
sample(s) to have a sample mean of exactly 188 days.
sample(s) to have a sample mean of 188 days or less.
sample(s) to have a sample mean of 188 days or more.
