A sample of 10,000 electrical measurements has a mean of 380 kilovolts and standard deviation = 5 kilovolts. The measurement does not follow any particular distribution. (a). use Tchebysheff's theorem to find the range of measurements [low, high] so that probability will be at least 80%

(b). Use Tchebysheff's theorem to find the measurement value that will be greater than at most 5% of the time
