Each month the National Association of Purchasing Managers publishes the NAPM index. One of the questions asked on the survey to purchasing agents is: "Do you think the economy is contracting?" Last month, 170 of the 300 respondents answered yes to the question. This month, 160 of the 300 responses indicated they felt the economy was contracting. Can we conclude that the proportion of the agents that believe the economy is contracting this month is different than that of last month at the 10% significance level? Find the p-value for the appropriate hypothesis test
