According to the U.S. Census Bureau, there is a specific definition of poverty used by United States government. Each year the Census Bureau sets poverty levels. Depending on the size of a family, there is a specific amount of income, called the poverty threshold, below which a family is considered poor. We will cross-tabulate poverty and race from a sample of 100 U.S. citizens using data from 2015. The results are given in the following table.

	Poor (Below Poverty Line)	Not Poor (Above Poverty Line)	Total
People of Color (POC)	8	29	37
White	6	57	63
Total	14	86	100

1. Calculate the following probabilities from your data.

P(Poor)	P(Poor|POC)	P(Poor|White)
P(Not Poor)	P(Not Poor|White)	P(Not Poor and POC)
P(White| Not Poor)	P(White or POC)	P(White or Poor)

2. Is there a difference in Poverty rate due to race? Compare the results of question 1

3. A poll of American registered voters was taken by Politico/Morning Consult in November, 2017 after the Las Vegas mass shooting, in which 58 concertgoers were murdered by a single gunman. The poll asked the question, "Do you support or oppose stricter gun laws in the United States? The results of the poll, cross-tabulated by gender, are shown in the contingency table.

a. Combine the strong and somewhat groups for both support and oppose, and fill in the missing boxes.

	Support	Oppose	Don't Know	Total
Male			54	930
Female			73	1065
Total			127	1995

b. What percentage of all registered voters support (strong or somewhat) stricter gun laws?

c. What percentage of males support (strong or somewhat) stricter gun laws?

d. What percentage of females support (strong or somewhat) stricter gun laws?

e. Are gender and support of stricter gun laws independent events? Explain
