A woman gave birth 310 days after a visit from her husband who was in the Navy. Assume length of pregnancies are
normally distributed with mean 268 days and standard deviation 14 days. Consider a value unusual if it is beyond
two standard deviations from the mean.
1. How many standard deviations was this woman's length of pregnancy away from the mean?
2. What is the standard unit?
3. Is her length of pregnancy considered unusual? Statisticians don't believe in rare events so if something is
unusual, they believe there is a better explanation. Write any comments.
