Researchers Are Interested in Investigating the Effect of a Drug

Question 1

Multiple Choice

Researchers are interested in investigating the effect of a drug that is to be used in the treatment of patients who have glaucoma (an eye disorder associated with high eye pressure) . The goal of the drug is to reduce eye pressure. In a volunteer sample of 35 patients with glaucoma in both eyes, one eye of each patient was randomly assigned to this drug, and the other eye was given a placebo. After one week, the eye pressure was measured on each eye. The difference in eye pressure between the two eyes (drug - placebo) was measured for each patient. The sample mean difference in eye pressure was -1.21 mmHg (millimeters of mercury) , and the sample standard deviation of the differences was 4.67 mmHg.
-What are the null and alternative hypotheses for this scenario? Use drug - placebo for the direction of the difference.
