Use the Empirical Rule. The mean speed of a sample of vehicles along a stretch of highway is 63 miles per hour, with a standard deviation of 4 miles per hour. Estimate the percent of vehicles whose speeds are between 55 miles per hour and 71 miles per hour. (Assume the data set has a bell-shaped distribution.) Approximately % of vehicles travel between 55 miles per hour and...
