2. The Fair Labor Standards Act was passed in 1938. Since then, the standard work week in the United States has been 40 hours. In recent years, the standard work week has fallen to less than 40 hours in most of Western Europe and in Australia. Many believe that the work-oriented culture in the U.S. has resulted in pressure among workers to put in longer hours than the 40-hour standard. In industries such as investment banking, a 40-hour work week is considered "slacker" behavior and may result in losing a job. Is the average number of hours worked per week in the U.S. 40 hours, or has this changed? For those working in 2014, the GSS asked adult Americans: "How many hours did you work last week?" The summary statistics can be found in the GSS: sda.berkeley.edu/GSS using No Weight as default Type HRS1 in Row: and YEAR(2014) in Selection Filter: Under Output Options, uncheck Column under Percentaging and check Summary Statistics. Under Chart Options, select Bar Chart under Type of Chart, then Run the table. You will need these summary statistics for your work in StatCrunch. a) Use StatCrunch to find a 95% confidence interval for the average hours worked weekly in the U.S.. Include a check of the necessary conditions in your answer. Copy and paste the output from StatCrunch. b) Interpret your interval in context. c) Can you conclude that the average number of hours worked per week in the U.S. is 40 hours, or has this changed? Explain using your confidence interval.
