Suppose that your wife is pregnant and due in 100 days. Suppose that the probability density distribution function for having a child is approximately normal with mean 100 and standard deviation 8. You have a business trip and will return in 85 days and have to go on another business trip in 107 days. You are able to cancel your second business trip and your boos tells you that you can return home from your 1st trip so that there is a 99% chance that you will make it back for the birth. When must you return home?
