Homework SourseI need some help I had statistics two years ago and I forgot
I need some help. I had statistics two years ago and I forgot what test to run. I have the average flight time from Hawaii to Los Angeles for the past twenty years. I need to run a test to show if flight times have increased or decreased over the past 20 years. I\'m using Statcrunch to run the test.

Solution
to test whether flight times have increased or decreased over the past 20 years, you should use one sample t test.
