Let u say that the fuel efficiency of a particular model car is normally distributed with a mean of 24.8 mpg, µ and a standard deviation of, = 3.8 mpg.
a. How often do you expect the mpg of a vehicle to be 17.2 mpg or lower? Show work like shown in the module with the function notation, finding the z-score. Draw graph, properly label axis, with the zscore axis underneath.
b. How often do you expect the mpg of a vehicle to be between 22 mpg and 24.8 mpg Show work like shown in the module with the function notation, finding the z-score. Draw graph, properly label axis, with the z-score axis underneath.
