A double-blind experiment is conducted to test the effectiveness of a new drug in treating strep throat infections. The drug was administered to 4 patient groups with severe strep throat symptoms over the course of 8 weeks. The first patient group received a placebo (no drug), the 2nd group received a 200 mg/day dose of the drug, the 3rd group received 300 mg/day dose, and the 4th group received a 400 mg/day dose. Over the course of the 8- week treatment, scientists analyzed the level of infection in each patient group and found a direct correlation between the drug dosage and strep throat recovery time, with the 4th patient group recovering the fastest. This correlation was also seen in an almost identical experiment in which the drug was administered over a 4- week period (all other factors remained the same). In these experiments, the dependent variable(s) is/are Strep throat recovery time O Drug dosage AND length of treatment O The length of treatment O The drug dosage
