Question

An exit poll at an election of 1000 voters shows that 540 voted for Homer Simpson. Of course, Homer is guaranteed to win the election if more than half of the population voted for him (or the population proportion p> 0.5). Can Homer claim victory at the 0.05 level of significance? What is the p-value of the test statistic? (9 points)

Homer is guaranteed to win the election if more than half of the population voted for him.

let p₀ be the population proportion of voters who voted from Homer. The total number of voters, n=1000,

We want to test the following hypothesis,

H_o : p = 0.5 vs H₁: p > 0.5

Here, level of significance = 0.05
