Assignment  1
[1]  Download the data file  CHICK6.csv  from  Assignment  1.
[2] Load the CHICK6.csv data into R and rename it so that it includes your own name or initials (for example,
we might name our dataset  JunfuCHICK6 ).
[3] Generate the mean and the standard deviation for the variables Y, PC, PB, and YD  from the CHICK6.csv
data set.
[4]  You are going to run a  regression  (in  [5])  where  Y  is the dependent variable,  and  PC,  PB,  and  YD  are
the independent variables.  Discuss whether you think the independent variable  PB  will have a  negative or
positive effect on the dependent variable.  In  your  decision,  try  to  use  as  much  economic  theory  as  you  can  —
theory is what motivates what variables are included in a  model and what sign we anticipate for the model’s
[5]  Estimate the model in  R  and present the results.
[6]  Interpret the results for the coefficient  PB  from your model.  Make sure to include whether or not the
result aligned with your expectations.
