The lengths of human pregnancies are normally distributed with a mean of u = 268 days and a standard deviation of o = 15 days. What is the probability that a randomly selected pregnancy will last less than X 270 days? Find the z-score and then the probability that X is less than 270. Write the z-score rounded to 2 places and the your answer as a decimal rounded to 4 places. Z-score [ Choose ] Probability that X is less than 270 [ Choose ]
