Problem 18BSC

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?

Step-by-Step Solution:
Step 1 of 3

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 times required to taxi out for takeoff (in minutes) Frequency Relative frequency 10 – 14 10 15 – 19 20 20 – 24 9 25 – 29 1 30 – 34 2 35 – 39 2 40 – 44 2 45 - 49 2 Total 48 100%

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.
