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?
Problem 28BSC
Answer:
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

“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.
