4. A manufacturer of pipe had their quality-control department sample 600 ten-foot lengths. At a point 1 foot from the end of the pipe they measured the outside diameter. The mean of this diameter was 14 inches and the standard deviation was 0.1 inches. a. Using Chebyshev's Theorem, at least what percentage of the observations of the outside diameter will be between 13.85 and 14.15 inches? b. Using Chebyshev's Theorem, at least what percentage of the observations of the outside diameter will be between +-3 standard deviations from the mean?
