A study is conducted in which two learning conditions are compared. In one condition, 100 students are instructed to read the book before coming to class (Read Before Condition). In the other condition, 100 students are instructed to read the book after coming to class (Read After Condition). A manipulation check confirms that students followed these instructions. At the end of the quarter, learning is assessed by measuring each student's performance on the final exam. The researchers predicted that participants would perform better in the Read Before Condition than in the Read After Condition.

The researchers analyzed their data using null hypothesis significant testing. Assuming that they employed a non-directional or two-tailed test of significance, and an alpha of .05, what would have been their null hypothesis?

Group of answer choices:

a) That performance would be better in the Read Before Condition than in the Read After Condition

b) That performance would be better in the Read After Condition than in the Read Before Condition

c) That performance wouldn't be better in the Read Before Condition than in the Read After Condition

d) That performance would be the same in the two conditions
