A New York Times article titled For Runners, Soft Ground Can Be Hard on the Body considered two perspectives on whether runners should stick to hard surfaces or soft surfaces following an injury. One position supported running on soft surfaces to relieve joints that were in recovery from injury. The second position supported running on hard surfaces since soft surfaces can be uneven, which may make worse those injuries a soft surface was intended to help. Suppose we are given sufficient funds to run an experiment to study this topic. With no studies to support either position, which of the following hypotheses would be appropriate? The first position is more sensible, so this should be a one-sided test. In this case, we should form the alternative hypothesis around the second position. The second position makes the more sense, so this should be a one-sided test. In this case, we should form the alternative hypothesis around the first position. Because we would be interested in any difference between running on hard and soft surfaces, we should use a two-sided hypothesis test. Because there is uncertainty, we should postpone defining the hypotheses until after we collect data to guide the test.

Question
A New York Times article titled For Runners, Soft Ground Can Be Hard on the Body considered two
perspectives on whether runners should stick to hard surfaces or soft surfaces following an injury. One
position supported running on soft surfaces to relieve joints that were in recovery from injury. The
second position supported running on hard surfaces since soft surfaces can be uneven, which may make
worse those injuries a soft surface was intended to help.
Suppose we are given sufficient funds to run an experiment to study this topic. With no studies to
support either position, which of the following hypotheses would be appropriate?
The first position is more sensible, so this should be a one-sided test. In this case, we should form
the alternative hypothesis around the second position.
The second position makes the more sense, so this should be a one-sided test. In this case, we
should form the alternative hypothesis around the first position.
Because we would be interested in any difference between running on hard and soft surfaces, we
should use a two-sided hypothesis test.
Because there is uncertainty, we should postpone defining the hypotheses until after we collect
data to guide the test.
