The mean gas mileage for a hybrid car is 56 miles per gallon. Suppose that the gasoline mileage is approximately normally distributed with a standard deviation of 3.3 miles per gallon. (a) What proportion of hybrids gets over 60 miles per gallon? (b) What proportion of hybrids gets 51 miles per gallon or less? (0) 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 45 miles per gallon? (a) The proportion of hybrids that gets over 60 miles per gallon is '1. (Round to four decimal places as needed.) (b) The proportion of hybrids that gets 51 miles per gallon or less is |:. (Round to four decimal places as needed.) (c) The proportion of hybrids that gets between 58 and 61 miles per gallon is '1. (Round to four decimal places as needed.) (d) The probability that a randomly selected hybrid gets less than 45 miles per gallon is D. (Round to four decimal places as needed.)
