Question

Assume that 12 jurors are randomly selected from a population in which 77% of the people are Mexican-Americans. Refer to the probability distribution table below and find the indicated probabilities. x P(x) 0 0+ 1 0+ 2 0+ 3 0.0002 4 0.0014 5 0.0073 6 0.0285 7 0.0818 8 0.1712 9 0.2547 10 0.2558 11 0.1557 12 0.0434 Find the probability of exactly 5 Mexican-Americans among 12 jurors. P(x=5) = Find the probability of 5 or fewer Mexican-Americans among 12 jurors. P(x≤5) = Assume that any probability less than 5% is convincing enough evidence to suspect discrimination. Does 5 Mexican-Americans among 12 jurors suggest that the selection process discriminates against Mexican-Americans? Yes or No?
