Find the probability of exactly 8 Mexican-Americans among 12 jurors.
P(x=8)=P(x=8)=

Find the probability of 8 or fewer Mexican-Americans among 12 jurors.
P(x≤8)=P(x≤8)= Incorrect

Does the occurrence of 8 Mexican-Americans among 12 jurors suggest that the selection process discriminates against Mexican-Americans?

Expert Solution

Step 1

The probability distribution of number of Mexican-Americans (X) when 12 juror are selected from the population where 75% people are Mexican-Americans is given as:
