A major cab company in Chicago has computed its mean fare from O'Hare Airport to the Drake Hotel to be $ 29.76 , with a standard deviation of $ 4.03 . 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 ?56%75%84%89% of the fares lie between 21.70 dollars and 37.82 dollars. (b) According to Chebyshev's theorem, at least ?56%75%84%89% of the fares lie between 23.715 dollars and 35.805 dollars. (c) Suppose that the distribution is bell-shaped. According to the empirical rule, approximately ?68%75%95%99.7% of the fares lie between 21.70 dollars and 37.82 dollars. (d) Suppose that the distribution is bell-shaped. According to the empirical rule, approximately 68% of the fares lie between dollars and
