Speaking to a group of analysts in January 2006, a brokerage firm executive claimed that at least 61% of investors are currently confident of meeting their investment objectives. A UBS Investor Optimism Survey, conducted over the period January 2 to January 15, found that 58% of investors were confident of meeting their investment objectives. (CNBC, January 20, 2006). Assume the UBS Investor Optimism Survey collected information from 317 investors. What is the p-value for the hypothesis test?
