Having trouble with part D. Please show work if possible. Thank You!!!
Suppose the lengths of the pregnancies of a certain animal are approximately normally distributed with mean u = 127 days and standard deviation o = 12 days. Complete parts (a) through (f) below. A. If 100 independent random samples of size n = 24 pregnancies were obtained from this population, we would expect 5 sample(s) to have a sample mean of 123 days or less. O B. If 100 independent random samples of size n = 24 pregnancies were obtained from this population, we would expect sample(s) to have a sample mean of 123 days or more. C. If 100 independent random samples of size n = 24 pregnancies were obtained from this population, we would expect sample(s) to have a sample mean of exactly 123 days. (d) What is the probability that a random sample of 59 pregnancies has a mean gestation period of 123 days or less? The probability that the mean of a random sample of 59 pregnancies is less than 123 days is approximately 0.0052 (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 = 59 pregnancies were obtained from this population, we would expect sample(s) to have a sample mean of 123 days or less. O B. If 100 independent random samples of size n = 59 pregnancies were obtained from this population, we would expect sample(s) to have a sample mean of 123 days or more. O C. If 100 independent random samples of size n = 59 pregnancies were obtained from this population, we would expect sample(s) to have a sample mean of exactly 123 days.
