The length of human pregnancies is approximately normal with mean y = 206 days and standard deviation a = 16 days. Completo parts (a) through (n. SER <by diuppone a random sample et 27 human pregnancies is obtained. Describe the sampling diambulon of the sample mean length of pregnancies 10 The samping distribution of is w 200 and e;- 3.0712 (Round to four decimal places as needed) te) What is the probability that a random sample of 27 pregnancies has a mean pestation period of 200 days or ow?* The probability that the mean of a random sample of 27 pregnancies in less than 200 days is (Round to four decimal places as needed) interpret this probability Select the correct choice below and it in the answer box wihin your choice (Round to the nearest integer as needed) OA 100 independent random samples of size 27 pregnancies were obtained from this population, we would expect sample(s) to have a sample mean of exacty 260 days O 8. 100 independert random samples of size n=27 pregnancies were obtained from this population, we would expect sample(s) to have a sample mean of 200 days or more OC. 100 independent random samples of size 27 pregnancies were obtained from this population, we would expect samplelo) to have a sample mean of 200 days or los 1) What is the probability that a random sample of 50 pregnancies has a mean pestation period of 260 days or less? The probability that the mean of a random sample of 50 pregnancies is less than 200 days (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) CA. 100 independent random samples of size 50 pregnancies were obtained from this population, we would expect name() to have a sample mean of 200 days or more OB 100 independent random samples of siren= 50 pregnancies were obtained from this population, we would expect sample(s) to have a sample mean of 260 days or loss OC 100 independent random samples of siren 50 pregnancies were obtained from this population, we would expect samplote) to have a sample mean of exactly 260 days on le) What might you conclude of a random sample of 50 pregnancies resulted in a mean gestation period of 260 days or less? This result would be so the sample likely came from a population whose mean gestation period is 266 days
