Use the Empirical Rule. The mean speed of a sample of vehicles along a stretch of highway is 64 miles per hour, with a standard deviation of 3 miles per hour. Estimate the percent of vehicles whose speeds are between 61 miles per hour and 67 miles per hour. (Assume the data set has a bell-shaped distribution.) Approximately % of vehicles travel between 61 miles per hour and 67 miles per hour.
