1. What would be the problem with looking at Chads bench press before and after testosterone injections? Why would a short time window be preferable to a long time window?

Group of answer choices

a. Chad doesnt take any supplemental testosterone during the pre-period and the synthetic testosterone may still be in his system during the post period. Short time windows give us a larger n, which is good for precision.

b. Chad might not just take testosterone, maybe he is taking methandrostenlone too. The short time window means we can always use OLS.

c. Its likely Chad would have gotten weaker over time without the testosterone injections. There is less potential for problematic changes over a short time window, that over a long time window.

d. Its likely Chad would have continued to get stronger over time, even without the testosterone injections. There is less potential for problematic changes over a short time window, that over a long time window.

e. Chads workout partner Brad might be doing confounding things during the pre and post period. Short time windows give us a larger n, which is good for precision.

2. True of False: We never actually get to see an individuals counterfactual. We get to see them with the treatment, or without it. The counterfactual exists in a parallel universe we cant actually see without a crystal ball.
