The lengths of a particular animal's pregnancies are approximately normally distributed, with mean u= 271 days and standard deviation o = 20 days. (a) What proportion of pregnancies lasts more than 306 days? (b) What proportion of pregnancies lasts between 266 and 276 days? (c) What is the probability that a randomly selected pregnancy lasts no more than 246 days? (d) A "very preterm" baby is one whose gestation period is less than 221 days. Are very preterm babies unusual? Click the icon to view a table of areas under the normal curve. (a) The proportion of pregnancies that last more than 306 days is. (Round to four decimal places as needed.)

Human pregnancies of healthy singleton fetuses (i.e., excluding pregnancies with early-term complications or miscarriages, and multiple births) are normally distributed with a mean of 266 days and a standard deviation of 13 days.
