Which hypothesis is correctly formatted regarding the effect of room temperature on student quiz scores? Options: If the room is colder, then students will have higher quiz scores., Cold rooms make for lower quiz scores., If quiz scores are related to room temperature, then a decrease in room temperature will cause an increase in quiz scores., If room temperature causes low quiz scores, then students will do worse on quizzes.

• If the independent variable changes the dependent variable will change
• If the independent variable is related to the dependent variable, then (specific change) in the independent variable will cause (specific change) in the dependent variable.
• If the dependent variable is related to the independent variable, then (specific change) in the dependent variable will cause (specific change) in the independent variable.
