A medical researcher wants to test the effectiveness of a new drug in treating a certain disease. They randomly assigned 100 patients to two groups: one group received the new drug, and the other group received a placebo. After a month, they measured the patients' symptom severity on a scale of 1 to 10. The researcher found that the mean symptom severity score for the group that received the new drug was lower than the mean score for the group that received the placebo. How can the researcher test the hypothesis that the new drug is effective in treating the disease? What statistical test should they use?
