In order to assess whether compensating for transportation costs and loss in wages increases the uptake of male circumcision in Zambia, a research team is planning to conduct a randomized controlled trial in Makululu District. The study plans to provide food and transportation vouchers as an incentive to the uncircumcised male population aged 15-49 years. The research team can only afford a sample size of 1,000 individuals in total. Fifty per cent will be randomly assigned to the treatment group and the other 50% to the control group. Following a pilot phase, the team found that 3% of individuals in the target population were already circumcised before the intervention. Using a one-side hypothesis test at the 0.05 significance level, calculate the MDE for a study with 80% statistical power. Hint: Recall that σ!= p (1-p)
