15. Thirteen jurors are randomly selected from a population of 5 million residents. Of these 5 million residents, it is known that 42% are of a minority race. Of the 13 jurors selected, 2 are minorities. (a) What proportion of the jury described is from a minority race? (b) If 13 jurors are randomly selected from a population where 42% are minorities, what is the probability that 2 or fewer jurors will be minorities? (c) What might the lawyer of a defendant from this minority race argue? (a) The proportion of the jury described that is from a minority race is (Round to two decimal places as needed.) (b) The probability that 2 or fewer out of 13 jurors are minorities, assuming that the proportion of the population that are minorities is 42%, is (Round to four decimal places as needed.) (c) Choose the correct answer below. O A. The number of minorities on the jury is impossible, given the composition of the population from which it came. O B. The number of minorities on the jury is unusually low, given the composition of the population from which it came. O C. The number of minorities on the jury is reasonable, given the composition of the population from which it came. O D. The number of minorities on the jury is unusually high, given the composition of the population from which it came.
