2. Thirty-year ?xed mortgage rates in April 2007 seemed normally distributed with mean 6.17%.14 The standard deviation is believed to be 0.25%. Find a bound such that the probability that the actual rate obtained will be this number or below it is 90%.
3. A project consists of three phases to be completed one after the other. The duration of each phase, in days, is normally distributed as follows: Duration of Phase I - N(84, 32); Duration of Phase II - N(102, 42); Duration of Phase III - N(62, 22). The durations are independent.
