Two types of medication for hives are being tested. The manufacturer claims that the new medication A is more effective than the standard medication B and undertakes a comparison to determine if medication A produces relief for a higher proportion of adult patients within a 40-minute time window. In a random sample of 40 adults given medication A, 34 were symptom-free after 40 minutes. In a random sample of 34 adults given medication B, 28 were symptom-free after 40 minutes. The hypothesis test is to be carried out at a 1% level of significance. Please make sure you have answered all questions in this part prior to submitting.
