Lesson Summary:

In part two of Chebychev's Theorem, the focus is on solving an example problem involving commuting distances in Mobile, Alabama. The theorem provides a formula for finding the interval of at least 50% of the population, given the mean and standard deviation. By using this formula and unit conversion, it is possible to find the distance in miles and calculate the interval, which in this case is between 65.4 and 78.6 miles per week.
