Hypothesis testing-two sample z test for proportion

Reference no: EM13106512

1. To compare the effectiveness of two treatments 1 and 2 for a particular disease. Patients were separated in 2 treatment groups. A patient in group 1 received treatment 1 and patients in group 2 received treatment 2. The results are given in the table below:

Treatment 1 Treatment 2

Success 170 180

Failure 30 10

(a) To answer the following question "Do treatments 1 and 2 have different effectiveness?", which test statistic should we use?

(b) A student, to whom the problem had been submitted, replied affirmatively to the question asked. Is the answer correct?
