Racism, juries, and interactions: In a study of racism, Nail, Harton and Decker (2003) had participants read a scenario in which a police officer assaulted a motorist. Half the participants read about an African American officer who assaulted an European American motorist, and half read about a European American officer who assaulted an African American motorist. Participants were categorized based on political orientation: liberal, moderate, or conservative. Participants were told that the officer was acquitted on assault charges in state court but found guilty of violating the motorist’s rights in federal court. Double jeopardy occurs when an individual is tried twice for the same crime. Participants were asked to rate, on a scale of 1-7, the degree to which the officer had been placed in double jeopardy by the second trial. The researchers reported the interaction as F= (2,58)=10.93, p<0.0001. The means for the liberal participants were 3.18 for those who read about the African American officer and 1.91 for those who read about the European American officer. The mean for the moderate participants were 3.50 for those who read about the African American officer and 3.33 for those who read about the European American officer. The means for the conservative participants were 1.25 for those who read about the African American officer and 4.62 for those who read about the European American officer.

a. Draw a table of cell means that includes that actual means for this study.

b. Do the reported statistics indicate that there is a significant interaction? If yes, describe the interaction in your own words.

c. Draw a bar graph that depicts the interaction. Include lines that connect the tops of the bars and show the pattern of the interaction.

d. Is this quantitative or qualitative interaction? Explain

e. Change the cell mean for the conservative participants who read about an African American officer so that this is now a quantitative interaction.

f. Draw a bar graph that depicts the patter that includes the new cell means

g. Change the cell means for the moderate and conservative participants who reads about an African American officer so that there is now no interaction.

h. Draw a bar graph that depicts the pattern that includes the new cell means.

Although Latin America countries have been relying on fiscal rules, there is ample evidence that incumbents engage in what we call political budget cycles. That is, increasing fiscal deficit to boost the economy before elections in order to appear competent and therefore increase the chances of being re-elected.

Do you think the legislature has a role? Which fiscal rules do you propose to eliminate the political budget cycles in Latin America?

Hints: 1) you can review the US states fiscal rules. 2) fiscal rules A and B may not be as effective, but together A and B may be very effective.

The percent of fat calories that a person in America consumes each day is normally distributed with a mean of about 36 and a standard deviation of about ten. Suppose that 16 individuals are randomly chosen. a.) TRUE or FALSE: The random variable is defined as the average percent of fat calories consumed each day by a person in America. b.) For a sample of size 16, state the mean of the sample mean. c.) For a sample of size 16, state the standard deviation of the sample mean (the "standard error of the mean"). d.) Suppose a sample of size 16 is taken. Find the probability that the average percent of fat calories consumed is more than 30.

Iron Man, Captain America and Thor have the following utilities for wealth:

Iron Man : U(W) = W

Captain America : U(W) = 10√ W

Thor : U(W) = W2/100

Suppose all are faced with the following gamble: with probability 50/50 their wealth is either $100 or $0.

1. Calculate the expected utility of the gamble for each individual.

2. What can you say about the risk associated with these preferences? Are these individuals risk averse, risk neutral or risk lovers?

3. If each individual could choose either to participate or not in the gamble, what would each person choose to do?

3) Discuss your own point of view on polygamous marriage arrangements. You may wish to think about last week’s readings regarding love and open marriages, for example, or serial monogamy. What do you think of the fact that in America, a man could have an affair with many women and even have many children out of wedlock and not be considered a criminal, whereas “polygamy” seems threatening to the authorities? And finally, do you think people should have the right to live in polygamous family units in America? Do you think the government has the right to ban certain forms of marriage? Why or why not?
