Question 630769: 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, of the 300 responses, 160 answered yes to the question. This month, 170 of the 290 responses indicated they felt the economy was contracting.At the .05 significance level, can we conclude that a larger proportion of the agents believe the economy is contracting this month?
