Find the probability that xis between three and nine.

An expert witness for a paternity lawsuit testifies that the length of a pregnancy is normally distributed with a mean of 280days and a standard deviation of 13days. An alleged father was out of the country from 240to 306days before the birth of the child, so the pregnancy would have been less than 240days or more than 306days long if he was the father. The birth was uncomplicated, and the child needed no medical intervention. What is the probability that he was NOT the father? What is the probability that he could be the father? Calculate the localid="1653472319552" z-scores first, and then use those to calculate the probability.

Suppose X ~ N(8, 1). What value of x has a z-score of 鈥�2.25?
