Refer to your text MROZ data set (posted under the \"Additional Resources\" section of our course) and use Excel's regression data analysis tool or State to compute the answers to the questions asked. Consider the following model: log(wage) = Bo + B1educ + u (1), where wage is hourly wage and educ is years of schooling. Assume that motheduc (mother's education) is uncorrelated with u. Next, use motheduc as an IV for educ to test for endogeneity of educ in (1), using only the working women in the sample. You nd that the t test is equal to and conclude that educ is endogenous at the 5% level of significance: . (NOTE: Write your rst answer in number format, with 2 decimal places of precision level; do not write your answer as a fraction. Add a leading minus sign symbol, a leading zero and trailing zeros when needed. Use a period for the decimal separator and a comma to separate groups of thousands. For your second answer, write either YES or NO. HINT: See Example 15.7.)
