a. According to Chebyshev's theorem, at least 1- (1/1.5)^2 = 55.555% of the fare lies within 1.5 standard deviations of the mean, 25.35 dollars.

\n" ); document.write( "b. Suppose that the distribution is bell shaped. If aproximately 99.7% of the fares lie between 14.67 dollars and 36.03 dollars, then the approximate value of the standard deviation for the distribution, according to the empirical rule is (36.03-14.67)/6 = 3.56_
