You are studying a new medication for chronic headaches. For each patient, you measure the improvement in their headache symptoms on a scale from 0 to 10 after taking the new medication. In a sample of 30 random patients, the mean improvement was 5.6 points, and the standard deviation was 2.8 points. Suppose the current best medication is known to give a mean improvement of 5 points for patients with chronic headaches. Perform a hypothesis test to investigate whether the new medication gives a higher mean improvement than the current best medication
