In recent years more people have been working past the age of 65. In 2005, 27% of people aged 65-69 worked. A recent report from the Organization for Economic Co-operation and Development (OECD) claimed that the percentage working had increased (USA Today, November 16, 2012). The findings reported by the OECD were consistent with taking a sample of 600 people aged 65-69 and finding that 180 of them were working. a. Develop a point estimate of the proportion of people aged 65-69 who are working. b. Set up a hypothesis test so that the rejection of Ho will allow you to conclude that the proportion of people aged 65-69 working has increased from 2005. c. Conduct your hypothesis test using a = .05. What is your conclusion?
