7. Ethical guidelines for statistical practice In recent years, the price of gasoline has become increasingly more expensive. Consequently, one of the major factors considered by consumers when purchasing a new vehicle is mpg (miles per gallon). Suppose that a vehicle manufacturer has created a new, more fuel-efficient vehicle and wants to estimate the vehicle's mean mpg highway (that is, me when driven only on the highway). It is in the manufacturer's best interest that the vehicle has a mean of at least 25 mpg highway The manufacturer tests a random sample of vehicles to determine their mpg when driven only on the highway and finds that the sample mean is 21 mpg highway. The manufacturer decides to test another (Independent) random sample of the same size and determines the second sample's mean is 27 mpg highway The ethical practice for the manufacturer is to report an estimated mean of because it This result because it is than the desired mean of 25 mpg highway
