Scientific Methоd A rаndоmized, cоntrolled clinicаl triаl has found that an inexpensive and commonly used steroid (Dexamethasone) can save the lives of people seriously ill with COVID-19. The drug, called Dexamethasone, is the first shown to reduce deaths from the coronavirus. This medication decreases the body's natural defensive response and reduces infection accompanied symptoms such as swelling and allergic reactions and immune system overdrive. METHODS In this controlled trial, we randomly divided and assigned patients to 2 groups: Group 1: Receive Dexamethasone for up to 10 days Group 2: Receive usual care alone In the graph below, we report the preliminary results of this comparison. What was the hypothesis tested in this clinical trial? [q1] What is the dependent variable in this experiment? [q2] What is the independent variable in this experiment? [q3] Which group is the control group? [q4]
