Determining Whether a Jury Selection Process Is Biased Assume that 12 jurors are randomly selected from a population in which 80% of the people are Mexican-Americans. Refer to Table 5-1 and find the indicated probability.
a. Using the probability values in Table 5.1, find the probability value that should be used for determining whether the result of 11 Mexican-Americans among 12 jurors is usually high.
b. Does the selection of 11 Mexican-American jurors suggested that the selection process favors Mexican-Americans? Why or why not?
