If we are interested in the impact of Chinese import competition (D_Imports_Per_Worker), why do we include other variables in the regression?

You should discuss the following topics in a cohesive reports, not an itemized list:

When aplha is .01 wha can we say that D_Imports_Per_Worker has an impact on each y-variable?

Pick one of the regressions and discuss what does the coefficient on years2000_2010 tell you?

How much would the unemployment rate go up for those without a college education if a region had a value of D_Imports_Per_Worker = $1000.

Discuss who seemed to be hurt the most by impacted by Chinese import competition.

Answer #1

D_Imports_Per_Worker (x1) is significant ( p-value is less than alpha=0.01) in the regression model to know the Chinese_import_competition (y) at alpha=0.01, so we can include other variable to look the wether the included variable is significant.

years2000_2010 (x5) is singificant predictor for response variable y, as the p-value is less than alpha=0.01.

since the coefficent of x1 = -0.107697625, if x1=1000 then change in unemployment (y)when College_Educated (x3)=0

so requiered change in y=-0.107697625*1000+0*0.022201975=107,69

years2000_2010 is most hurt as its its t-value is negative and highest.
