3.29 Assume that the Anniston, Alabama, data in Table 3.1 follow a normal distribution. Use the standard normal distribution in Table B.1 to determine the rain depth that would have a recurrence interval of 100 years. Use the same table to estimate the recurrence interval of the 1988 annual rain of 99 inches.
