Suppose you are a lawyer representing a Hispanic individual in a
criminal trial. Twelve jurors are randomly selected by the state
from a population that you know to be 50% Hispanic.
a. How many jurors would you expect to be Hispanic?
b. The select process produces a jury with 2 Hispanic individuals
What proportion of the jury is Hispanic? (Enter your answer as a
decimal, rounded to four decimal places)
c. Use the binomial distribution and find the probability that 2 or
fewer jurors would be Hispanic.
d. Create a graph of the distribution with the area corresponding
to the previous answer shaded in. Choices for creating a graph
include: Excel, Binomial Distribution Calculator (in resources
menu), TI-84 (take a pic), hand drawn, other software, websites.
Upload your finished graph below.

b) Suppose there is a group of individuals on which
you have individual-level data. Suppose, for those with wages below
some level ˜w, a policy is implemented to have them work more. You
have in your data hours worked, several individual characteristics,
the wages, and year. The policy is implemented in the year 2000,
and you have data for the year 1998 and 2002.
What type of estimation strategy would you use to
determine the effect of the policy?...
