Fuel economy estimates for automobiles built one year predicted a mean of 25.8 mpg and a standard deviation of 7.2 mpg for highway driving. Assume normal model.
What is the probability that a randomly selected automobile built this particular year gets more than 16.44 mpg? (round 4 decimals)
The lowest 2.5% of gas mileages of automobiles built this particular year get less than how many miles per gallon? (round 1 decimal)
