You love the new elliptical machines your gym added several months ago, but because they are so popular with other members too, you usually have to wait for a machine to become available. Out of curiosity, each day you write down how many minutes you have to wait for an elliptical machine. Using a confidence level of 80%, is the average wait time for an elliptical machine less than 5 minutes?

Is this a left-tailed, right-tailed, or two-tailed test?
Here we have asked to find the average wait time for an elliptical machine less than 5 minutes.
That is < 5
Hence we can say that this is left tail test.
Hope this will help you. Thank you :)
