Problem 76E

Unemployment and a reduced workweek. In an effort to increase employment, France mandated in February 2000 that all companies with 20 or more employees reduce the workweek to 35 hours. The economic impact of the shortened workweek was analyzed in Economic Policy (July 2008). The researchers focused on several key variables such as hourly wages, dual-job holdings, and level of employment. Assume that in the year prior to the 35-hour-workweek law, unemployment in France was at 12%. Suppose that in a random sample of 500 French citizens (eligible workers) taken several years after the law was enacted, 53 were unemployed. Conduct a test of hypothesis to determine if the French unemployment rate dropped after the enactment of the 35-hour-workweek law. Test using  = .05.

ANSWER:

Solution:

Step 1 of 2:

A random sample of 500 French citizens taken several years after the law was enacted, 53 were unemployed.

The year prior to the 35-hour- workweek law, unemployment in France was at 12%.

We have to conduct a test of hypothesis to determine if the French unemployment rate dropped after the enactment of the 35-hour-workweek law, if
