Suppose the lengths of the pregnancies of a certain animal are approximately normally distributed with mean ji = 191 days and standard deviation o = 19 days. Complete parts (a) through (?) below. (c) What is the probability that a random sample of 17 pregnancies has a mean gestation period of 185 days or less? The probability that the mean of a random sample of 17 pregnancies is less than 185 days is approximately 0.0968 (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.) @A. If 100 independent random samples of size n = 17 pregnancies were obtained from this population, we would expect 10 sample(s) to have a sample mean of 185 days or less. O B. If 100 independent random samples of size n = 17 pregnancies were obtained from this population, we would expect sample(s) to have a sample mean of 185 days or more. O G. If 100 independent random samples of size n = 17 pregnancies were obtained from this population, we would expect sample(s) to have a sample mean of exactly 185 days. (d) What is the probability that a random sample of 43 pregnancies has a mean gestation period of 185 days or less? The probability that the mean of a random sample of 43 pregnancies is less than 185 days is approximately 0.0191 (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 = 43 pregnancies were obtained from this population, we would expect sample(s) to have a sample mean of exactly 185 days. O B. If 100 independent random samples of size n = 43 pregnancies were obtained from this population, we would expect sample(s) to have a sample mean of 185 days or more. &C. If 100 independent random samples of size n = 43 pregnancies were obtained from this population, we would expect 2 sample(s) to have a sample mean of 185 days or less. (e) What might you conclude if a random sample of 43 pregnancies resulted in a mean gestation period of 185 days or less? This result would be unusual, so the sample likely came from a population whose mean gestation period is less than 191 days. (f) What is the probability a random sample of size 18 will have a mean gestation period within 8 days of the mean? The probability that a random sample of size 18 will have a mean gestation period within 8 days of the mean is (Round to four decimal places as needed.)
