(7 points) The mean time in a men's 400-meter dash is 48.45 seconds, with a standard deviation of 3.55 seconds. Apply Chebychev's Theorem to the data to find the interval that contains at least 88.9% of all times in the men's 400- meter dash. At least 88.9% of the times in the men's 400-meter dash are between sec and sec . Note: Use 2 decimal places in your answers.
