Question

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 (to 2 decimals).

b. Set up a hypothesis test so that the rejection of H₀ will allow you to conclude that the proportion of people aged 65-69 working has increased from 2005.
H₀: p - Select your answer -greater than or equal to .27greater than .27less than or equal to .27less than .27equal to .27not equal to .27Item 2
H_a: p - Select your answer -greater than or equal to .27greater than .27less than or equal to .27less than .27equal to .27not equal to .27Item 3

c. Conduct your hypothesis test using =.05.

p-value - Select your answer -greater than or equal to .05, rejectgreater than .05, do not rejectless than or equal to .05, rejectless than .05, do not rejectequal to .05, rejectnot equal to .05, rejectItem 4

What is your conclusion?
- Select your answer -Conclude that the proportion of people aged 65-69 has increased since 2007.Cannot conclude that the proportion of people aged 65-69 has increased since 2007.Item 5
