For an upcoming congressional election, suppose we want to estimate the amount of support for a particular candidate in a district. By previous experience and voter registration data, we can assume that the prior distribution, the proportion of support, p, is a beta distribution with α = 10, and β = 8 (i.e. π(p) ~ Beta (10, 8)). We conducted a survey of 1000 randomly selected voters, of whom 600 support the candidate. Test the hypothesis H0: p ≥ 0.60 versus Ha: p < 0.60.
