=+4. Choose a real-life activity (such as a machining operation) and collect a number of samples of the time the activity takes (40-50 will be sufficient). Compile a cumulative distribution for this set of samples according the steps outlined in this chapter.

Use the resulting graph and a table of random numbers to produce a series of values, and then construct a frequency distribution graph for these values. How well does this graph resemble that of the original data? (Remember that the number of random values generated should be sufficiently large.)
