PASSAGE
A randomized controlled trial is conducted to evaluate a new medication designed to reduce intraocular pressure (IOP) in patients with glaucoma. Sixty patients are randomly assigned to receive either the new medication or a placebo eye drop. After one month, the mean IOP is measured in each group. The data are approximately normally distributed.
Which statistical test is most appropriate to determine if there is a significant difference in the mean IOP between the medication and placebo groups?
