The mean gas mileage for a hybrid car is 57 miles per gallon. Suppose that the gasoline mileage is approximately normally distributed with a standard deviation of 3.5 miles per gallon. (a) What proportion of hybrids gets over 61 miles per gallon? (b) What proportion of hybrids gets 51 miles per gallon or less? (c) What proportion of hybrids gets between 58 and 61 miles per gallon? (d) What is the probability that a randomly selected hybrid gets less than 46 miles per gallon? Click the icon to view a table of areas under the normal curve. (a) The proportion of hybrids that gets over 61 miles per gallon is (Round to four decimal places as needed.)
