The lifetime of the battery of a certain make of cars is normally distributed with mean 5 years and standard deviation 6 months. An owner of this type of car wants to take a chance and replace the battery at the 3rd quartile of the distribution. In how many months he should have the battery replaced in case the battery lasts until then (round off to the nearest integer)?
