Use CPS_replicate.dta and replicate the following results and answer the questions. A detailed description of the data is given in CPS_replicate.pdf. In this exercise, you will investigate the trend in gender gap of earnings of college graduates in the U.S. Replicate the following result. In other words, using the data, produce the statistics reported in the following table. Manually calculate the standard error of difference reported in column (8) and 95% confidence interval for difference in column (9) for each five years. Show your work. Construct a 95% confidence interval for the change in men\'s average hourly earnings between 1992 and 2008. Construct a 95% confidence interval for the change in women\'s average hourly earnings between 1992 and 2008. Construct a 95% confidence interval for the change in the gender gap in average hourly earnings between 1992 and 2008. Based on the analysis answer the following questions: Is the gender gap large? Why? Did the estimated gender gap increased from 1992 to 2008? If so, how much? Is this increase statistically significant at the 5% level?
