A survey of a random sample of 184peoplein a city. The results show51% who would vote for Proposal X. The mayor, who is against the proposal,claims that the actual percentageof votersis less than 50%. Use the following steps to test the claim at a 0.05significance level. e.State the type of test (left tailed, right tailed, or two tailed).
