Figure 8-7. Histogram of the two-year sample

Based on the histogram, my guess of 75 to 85 percent would seem acceptable. More exact may be greater than 75 percent and less than or equal to 85 percent. If we look at a simpler view of the data spread, we find that the range offered is quite reasonable and probable. But again, the main test will be to check our ideas against customer feedback.

A simple frequency chart of the same data, shown in Figure 8-8, tests the visual interpretation and affirms the guess.
