Example 9: The lengths of pregnancies are normally distributed with a mean of 268 days and a standard deviation of 15 days. If we stipulate that a baby is. premature if the length of pregnancy is in the lowest 4%, find the length that. separates premature babies form those who are not premature.) Table A-2 is designed only for the standard normal distribution, which has a mean of 0 and a standard deviation of 1. II) Each value in the body of the table is the cumulative area from the left op to a vertical line above a specific value of z.
