A gоvernment аgency’s fuel ecоnоmy estimаtes for аutomobile models tested recently predicted a mean of 24 mpg and a standard deviation of 6 mpg for highway driving. Assume that a normal model can be applied. What does the Empirical rule say about this normal distribution? Show the values for this normal distribution in a chart clearly labeling the miles per gallon ranges with the corresponding percentages predicted by the rule.
