A study is conducted to investigate long-term complication rates in patients treated with two different therapies. Among 68 patients treated with therapy 1, 13 of them have experienced long-term complications. Among 60 patients treated with therapy 2, 16 of them have experienced long-term complications. Let P1 be the population proportion of patients with long-term complications among those treated with therapy 1, and p2 be the population proportion of patients with long-term complications among those treated with therapy 2. Consider the hypothesis testing problem Ho : Pi = P2 against Ha : pi # P2. Calculate the test statistic.

A study is conducted to investigate long-term complication rates in patients treated
with two different therapies. Among 68 patients treated with therapy 1, 13 of them
have experienced long-term complications. Among 60 patients treated with therapy
2, 16 of them have experienced long-term complications. Let Pi be the population
proportion of patients with long-term complications among those treated with
therapy 1, and p2 be the population proportion of patients with long-term
complications among those treated with therapy 2. Consider the hypothesis testing
problem
Ho : pi = P2 against Ha : pi # 2.
Calculate the test statistic.
