The length of human pregnancies is approximately normally distributed with mean 266 days and standard deviation 26 days. Consider taking samples of size n = 20; thereby, creating a Sampling Distribution. What is the probability that a random sample of 20 pregnancies will have a sample mean length more than 270 days? Use the normal probability graph below to label and shade the picture correctly for this problem. OA 0.2451 OB.0.7549 OC0.5596 O D.0.4404
