Only use the data from 1987 and 1988. Carefully study the data before you proceed. Construct the D-i-D estimator in different ways: (a) Run the regressionhrsempit = β0 + β1 grant it + β21( year = 1988) + β3Ei + uit where Ei is a dummy variable for being a treatment (i.e. someone who would receive the grant in 1988). (b) Run the fixed effect regression with firm fixed effects θi: hrsempit = θi + β1 grant it + β21( year = 1988) + uit (c) Construct the 4 means of controls and treatments, before and after, and es- timate the difference in difference with means.

4. Outliers can be detected using a statistical approach, one of popular approaches is the Inter Quartile Range (IQR) method. A sample is categorized as an outlier if its value is less than (Q1 - 1.5 * IQR) or greater than (Q3 + 1.5 * 1QR). Use these conditions to detect outliers in the following data: 130,132,138,136,131,153,131,133,129,133,110,132,129,134,135,132, 135,134,133,132,130,131,134,135,135,134,136,133,133,130 note: Q1 = quartile 1, Q3 = quartile 3 Draw the Boxplot to show the outliers %3D
