what's the probability?
Suppose the lengths of the pregnancies of a certain animal are approximately normally distributed with mean p = 226 days and standard deviation o = 20 days. Complete parts (a) through (f) below. C. If 100 independent random samples of size n = 20 pregnancies were obtained from this population, we would expect sample(s) to have a sample mean of 219 days or less. (d) What is the probability that a random sample of 47 pregnancies has a mean gestation period of 219 days or less? The probability that the mean of a random sample of 47 pregnancies is less than 219 days is approximately (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 = 47 pregnancies were obtained from this population, we would expect sample(s) to have a sample mean of exactly 219 days. B. If 100 independent random samples of size n = 47 pregnancies were obtained from this population, we would expect sample(s) to have a sample mean of 219 days or less. C. If 100 independent random samples of size n = 47 pregnancies were obtained from this population, we would expect sample(s) to have a sample mean of 219 days or more (e) What might you conclude if a random sample of 47 pregnancies resulted in a mean gestation period of 219 days or less? This result would be so the sample likely came from a population whose mean gestation period is 226 days. (f) What is the probability a random sample of size 20 will have a mean gestation period within 9 days of the mean? The probability that a random sample of size 20 will have a mean gestation period within 9 days of the mean is (Round to four decimal places as needed.)
