Probability same question part C

The length of human pregnancies is approximately normal with mean u = 266 days and standard deviation o = 16 days. Complete parts (a) through (f) Jo. Il TOO pregnant maivrquals were selected moependeny from us population, we would expect pregnancies to fast less inan 250 days. O C. If 100 pregnant individuals were selected independently from this population, we would expect pregnancies to last exactly 258 days (b) Suppose a random sample of 10 human pregnancies is obtained. Describe the sampling distribution of the sample mean length of pregnancies The sampling distribution of x is with u = and ox = (Type integers or decimals rounded to four decimal places as needed ) (c) What is the probability that a random sample of 10 pregnancies has a mean gestation period of 258 days or less? The probability that the mean of a random sample of 10 pregnancies is less than 258 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 = 10 pregnancies were obtained from this population, we would expect sample(s) to have a sample mean of 258 days or more. O B. If 100 independent random samples of size n = 10 pregnancies were obtained from this population, we would expect sample(s) to have a sample mean of 258 days or less O C. If 100 independent random samples of size n= 10 pregnancies were obtained from this population, we would expect sample(s) to have a sample mean of exactly 258 days Click to select your answer(s) O L W 100%
