The number of potholes in any given 1 mile stretch of freeway pavement in Pennsylvania has a bell-shaped distribution. This distribution has a mean of 55 and a standard deviation of 9. Using the empirical rule, what is the approximate percentage of 1-mile long roadways with potholes numbering between 28 and 64?
