Response time is an important statistic for measuring the effectiveness of a fire department, and is measured as the
difference between the time a fire house receives a call and the time the first piece of fire equipment leaves the
station. The response times for fire departments in a large city are found to have an approximately Normal
distribution, with a mean of 4.5 minutes and a standard deviation of 1.2 minutes. What percentage of fire station
response times are between 4 and 6 minutes?
