The lengths of pregnancies are normally distributed with a mean of 266 days and a standard deviation of 15 days. a. In a letter to an advice​ column, a wife claimed to have given birth 307 days after a brief visit from her​ husband, who was working in another country. Find the probability of a pregnancy lasting 307 days or longer. What does the result​ suggest? b. If the length of pregnancy is in the lowest 3​%, then the baby is premature. Find the length that separates premature babies from those who are not considered premature.       a. The probability that a pregnancy will last 307 days or longer is enter your response here. ​(Round to four decimal places as​ needed.) What does the result​ suggest?     A. The result suggests that either a very rare event occurred or the husband is not the father.   B. The result suggests an uncommon but not significant event occurred.   C. The result suggests the event did not occur.
