(a) What is the probability that a randomly selected pregnancy lasts less than 259 days? The probability that a randomly selected pregnancy lasts less than 259 days is approximately (Round to four decimal places as needed.) CELIN interpret this probability. Select the correct choice below and fill in the answer box within your choice. (Round to the nearest integer as needed.) OA. if 100 pregnant individuals were selected independently from this population, we would expect OB. If 100 pregnant individuals were selected independently from this population, we would expect OC. If 100 pregnant individuals were selected independently from this population, we would expect (b) Suppose a random sample of 6 human pregnancies is obtained. Describe the sampling distribution of the sample mean length of pregnancies. The sampling distribution of x is with and a (Round to four decimal places as needed.) (c) What is the probability that a random sample of 6 pregnancies has a mean gestation period of 259 days or less? The probability that the mean of a random sample of 6 pregnancies is less than 259 days is (Round to four decimal places as needed.) pregnancies to last less than 259 days. pregnancies to last more than 259 days. pregnancies to last exactly 259 days.
Interpret this probability. Select the correct choice below and fill in the answer box within your choice. (Round to the nearest integer as needed.) OA. If 100 independent random samples of size n-6 pregnancies were obtained from this population, we would expect OB. If 100 independent random samples of size n-6 pregnancies were obtained from this population, we would expect OC. If 100 independent random samples of size n-6 pregnancies were obtained from this population, we would expect (d) What is the probability that a random sample of 35 pregnancies has a mean gestation period of 259 days or less? The probability that the mean of a random sample of 35 pregnancies is less than 259 days is (Round to four decimal places as needed.) sample(s) to have a sample mean of 259 days or less. sample(s) to have a sample mean of exactly 259 days sample(s) to have a sample mean of 259 days or more. Interpret this probability. Select the correct choice below and fill in the answer box within your choice. (Round to the nearest integer as needed.) OA If 100 independent random samples of size n-35 pregnancies were obtained from this population, we would expect sample(s) to have a sample mean of 259 days or more. OB. If 100 independent random samples of size n-35 pregnancies were obtained from this population, we would expect sample(s) to have a sample mean of exactly 259 days. OC. If 100 independent random samples of size n-35 pregnancies were obtained from this population, we would expect sample(s) to have a sample mean of 259 days or less (e) What might you conclude if a random sample of 35 pregnancies resulted in a mean gestation period of 259 days or loss? This result would be so the sample likely came from a population whose mean gestation period is 266 days
(1) 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.)
