The histogram below shows the distribution of gas mileage in miles per gallon (MPG) from 14 users who drive a 2012 Toyota Prius. The sample mean is 53.3 MPG and the standard deviation is 5.2 MPG. Note that these data are user estimates and since the source data cannot be verified, the accuracy of these estimates are not guaranteed. 6 4 2 0 40 45 50 55 Mileage (in MPG) 60 65 (ay The EPA claims that a 2012 Prius gets 50 MPG [city and highway mileage combined).
