    Help with Chebyshev's theorm!

    From years of experience fishing for trout in the Yellowstone River you know that the mean length of trout you catch is 14.7 inches with a standard deviation of 1.5 inches.
    A) Use Chebyshev's Theorm to find an interval A to B for the lengths of trout in which at least 75% of the fish you catch will fall.
    B)Compute the CV for this data.
    Please help me. Thank you

    Remember what Chubby Checkers says: Disregarding distribution, the percentage of values laying within K standard deviations from the mean will be 1 - \frac{1}{K^2}, for K greater than 1. Therefore, you can use Chubby's theorem to set up an equation:

    .75 = 1 - \frac{1}{K^2}

    And solve for K, which will give you how many standard deviations (to the left and right), a certain value is. These values will be the interval that corresponds to 75% of the data laying within K standard deviations of the mean.
