The figure illustrates a normal distribution for the prices paid for a particular model of a new car.The mean is $21,000 and the standard deviation is $2000, use the 68-95-99.7 ruled to find what percentage of buyers paid between $15,000 and $21,000
it's a graph as 15=99.7% 17= 9.5% 19= 68% 21= it's in the middle between 19 and 23 23=68% 25=9.5 27-99.7
