In December, General Motors produced 7,500 customized vans at its plant in Detroit. The labor productivity at this plant is known to have been 0.14 vans per labor hour during that month. 340 laborers were employed at the plant that month.
a) In the month of December the average number of hours worked per laborer =hours/laborer (round your response to one decimal place).
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 Ho will allow you to conclude that the proportion of people aged 65-69 working has increased from 2005.
