Problem 28BSC

Constructing Frequency Distributions. In Exercise, use the indicated data and construct the frequency distribution.

Flight Taxi-Out Times Refer to Data Set 15 in Appendix B and use the times required to taxi out for takeoff. Begin with a lower class limit of 10 min and use a class width of 5 min. Based on the result, does it appear that the time required to taxi out can be predicted with reasonable accuracy?

Step-by-Step Solution:
Step 1 of 3

Problem 28BSC

Step1 of 3:

We have Refer to Data Set 15 in Appendix B and use the times required to taxi out for takeoff. Begin with a lower class limit of 10 min and use a class width of 5 min. Based on the result.

Step2 of 3:

We need check does it appear that the time required to taxi out can be predicted with reasonable accuracy?

Step3 of 3:

The given data can be written in terms of class interval and it is given below

 CI frequency 10-15 10 15-20 20 20-25 9 25-30 1 30-35 2 35-40 2 40-45 2 45-50 2

“No”, because the last 5 classes have a very low (non-zero) frequency and thus the times do not seem to be centered about a certain value, which means that the time can not be predicted with reasonable accuracy.
