Explanation / Answer

A. In this, we need to test whether people who sleeps without curtains wakes up earlier than typical average so this would be a one tailed test.

B. In this, we are testing the claim whether farm animals raised in open pens are calmer than average so this would be a one tailed test.

C. The influence of stress can be negative as well as positive on student testing and hence, this will be a two tailed test.

D. It is not clear here in this case whether we will use one tailed or two tailed test because any quantitative value doesn't seem feasible in this statement.
