Page BreakUse the following for C,D and EThe Minimum Wage Law protects the right of workers to get a minimum wage. Consider a scenario where the law of minimum wage was changed just in the state of New Jersey (i.e., law has not been changed in other states). We want to use the data from company XYZ to observe the difference in hours worked by full time employees in New Jersey before and after the law was changed. Note: The variable 'State’ indicates the citizenship of the worker, i.e., State = New Jersey ,the worker is from NJ, else worker is not from NJ (is from Philadelphia). Note: The variable fte contains the number of hours worked by an employee. Note: The variable d indicates whether or not the data was collected before or after the law changed, i.e. d = 1 indicates the data was collected after the law was changed, and d = 0 indicates the data was collected before the law was changed.
