Interpreting Normal Quantile Plots. In Exercises 5–8, examine the normal quantile plot and determine whether the sample data appear to be from a population with a normal distribution.

Flight Departure Delays The normal quantile plot represents flight departure delay times (minutes) from Data Set 15 in Appendix B.

Answer :

Step 1 of 1 :

Given, The normal quantile plot represents flight departure delay times (minutes) from Data Set 15.

The claim is to determine whether the sample data appear to be from a population with a normal distribution.

Conclusion :

Not normal. The points are not reasonably close to a straight line pattern, and there appears to be a pattern that is not a straight line pattern.
