Download the data file CHICK6.csv from Assignment 1.
 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 ).
 Generate the mean and the standard deviation for the variables Y, PC, PB, and YD from the CHICK6.csv
 You are going to run a regression (in ) 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 eect 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 models
 Estimate the model in R and present the results.
 Interpret the results for the coefficient PB from your model. Make sure to include whether or not the
result aligned with your expectations.
