A new AIDS prevention drug was tried on a group of 224 HIV positive patients. Fortyfive patients developed AIDS after four years. In a control group of 224 HIV positive patients, 63 developed AIDS after four years. We want to test whether the method of treatment reduces the proportion of patients that develop AIDS after four years or if the proportions of the treated group and the unheated group stay the same. You will need to specify the appropriate hypothesis, name of statistical test, statistical result and the its interpretation in the given context. You will need to present the answer in the format that shows all the steps of hypothesis testing For example: Given? Step1: what is the parameter of interest? Provide notation. 'What is the hypothesis of interest? Step2: What method would you use to test the above hypothesis (stating the name of the function used in TIcalculator will suffice)? Provide brief reasoning for your choice. Step3: If using the pvaluemethod, then provide the name and value of the test statistic. If using the CImethod, then provide the name for the type of interval and its value. Step4: What do you conclude? Provide reasoning for your conclusion
