Final answer:
The question involves medicinal treatments for anxiety and allergies, comparing the effectiveness of two medications for hives using statistics at a 1 percent level of significance.
Step-by-step explanation:
The subject matter of this question appears to be related to Medicine, specifically pharmacology and the study of medication effects on anxiety and allergies. The scenario involves comparing the effectiveness of two medications for treating hives.
From the information given, we know that Xanax (alprazolam) is a medication from the benzodiazepine class, which is used to treat symptoms of anxiety. These medications can be short-acting and are often prescribed for short-term use to help control acute symptoms of anxiety. Furthermore, tolerance and withdrawal are two important considerations when using such medications.
In a clinical study described, Medication A and Medication B are being compared for effectiveness in treating hives. A statistical test, specifically a hypothesis test at a 1 percent level of significance, would be performed to determine if there's a statistically significant difference in the reaction rates between the two medications after 30 minutes.
