Is it true that a majority of teenagers put the scantron test on one side and the real test on the other? Or is it just a coincidence?
Is it true that a majority of teenagers put the scantron test on one side and the real test on the other? Or is it just a coincidence?
HypothesisHypothesis
If students take the scantron tests, then a majority of the students will move the scantron to the right and the real test to the left.
Null: If I give 50 students a scantron test there will not be a difference on what side of the test they put the scantron on.
