Flight Taxi-Out Times Use the relative frequency distribution from Exercise 28 in Section 2-2 to construct a histogram. If the quality of air traffic procedures were improved so that the taxiout
times vary much less, would the histogram be affected?
Solution 18BSC
In a relative frequency distribution, the relative frequency for a class obtain by dividing the corresponding class frequency with the total of all the given frequencies in that distribution and the resultant is multiply with 100%.
From the given information, the relative frequency distribution for the times required to taxi-out for takeoff (in minutes) is

The constructed Histogram for the above relative frequency distribution is as follows:
From the above histogram we can see that the taxi-out times vary much less, if the quality of air traffic procedures were improves so that the histogram is also affected.
