26. Do basketball players have lower ABILITY to make free-throws when shooting granny-style (underhanded)? Suppose that you go to a basketball
court and take 30 free-throws in random order-15 shots granny-style and
15 shots using the traditional style-and record the number of shots made
in each context.
(a) What are the explanatory and response variables in this experiment?
(b) What are the treatments in this experiment?
(c) Explain why it was important to randomize the order in which the shots
were taken.
(d) What variables are important to control (keep the same) during this
experiment?
(e) State the hypotheses you are interested in testing.
(f) If the experiment provides convincing evidence that you have a lower
ABILITY to make free-throws when shooting granny-style, can you conclude
that the shooting style is the cause? Explain.
