Question
A torn meniscus is a common type of knee injury. In the
case of minor tears, there’s some question about whether
initial surgery followed by physical therapy (PT) results
in a better outcome than just physical therapy alone.
To find out, experimenters will randomly assign some
subjects with this type of injury to have surgery followed
by PT and others to just do PT, and then compare the
recovery experiences of the tow groups. Which of
statements A–D is false?

gery was beneficial, they will commit a Type I error.
B) The power of this test is its ability to detect that there
really is a benefit of surgery.C) The more participants they use in this experiment, the
higher the power of the test will be.
D) Demanding stronger evidence by using a = 0.01
instead of a = 0.05 would give the researchers
greater power.
E) None; statements A–D are all true.
