Price of electricity: The Energy Information Administration records the price of electricity in the United States each month. In July 2013, the average price of electricity was 13.06 cents per kilowatt-hour. Suppose that the standard deviation is 1.30 cents per kilowatt-hour. What can you determine about these data by using Chebyshev's Inequality with K=3? At least % of the data fall between and cents per kilowatt-hour. X (Round answers to two decimal places as necessary.)
