Of the n = 1000 people in ACS, 761 are White, 106 are Black, 70 are Asian, and 63 are other races. The sample proportion of people who have health insurance for each racial group are p̂_white = 0.880, p̂_black = 0.811, p̂_asian = 0.843, and p̂_other = 0.730.
(a) Create the two-way table for counts of health insurance status by race.
(b) Produce a graph to visualize the relationship between health insurance status and race.
(c) Is there a significant association between whether or not a person has health insurance and race? State hypotheses, calculate a p-value, and make a conclusion in context.

The American Community Survey, administered by the US Census Bureau, is given every year to a random sample of about 3.5 million households (about 3% of all US households). It has been crucial for government and policy decisions, and helps to determine how over 400 billion dollars of government funds are distributed each year. Unfortunately, the House voted in May 2012 to eliminate this valuable source of information. Data on a random sample of 1% of all US residents are made public (after ensuring anonymity), and we have selected a random sub-sample of n = 1000 from the 2010 data, stored in ACS.
