A major cab company in Chicago has computed its mean fare from O'Hare Airport to the Drake Hotel to be $25.88, with a standard deviation of $4.96. Based on this information, complete the following statements about the distribution of the company's fares from O'Hare Airport to the Drake Hotel.

(a) According to Chebyshev's theorem, at least ?of the fares lie between 15.96 dollars and 35.80 dollars.

(b) According to Chebyshev's theorem, at least 36% of the fares lie between O dollars and O dollars. (Round your answer to 2 decimal places.)

(c) Suppose that the distribution is bell-shaped. According to the empirical rule, approximately 68% of the fares lie between dollars and dollars.

(d) Suppose that the distribution is bell-shaped. According to the empirical rule, approximately ?of the fares lie between 15.96 dollars and 35.80dollars.?
