Pregnancy Durations Data from the National Vital Statistics System reveal that the distribution of the duration of human pregnancies (i.e., the number of days between conception and birth) is approximately normal with mean 270 and standard deviation 17 days. Use this normal model and a table of standard normal probabilities to determine the proportion of all pregnancies that come to term (have a duration) in the following number of days. Round your answers to four decimal places. a. Less than 247 days (approximately 8 months). b. More than 272 days (approximately 9 months). c. More than 300 days. d. Between 260 and 280 days.
