Thirteen jurors are randomly selected from a population of 3 million residents. Of these 3 million residents, it is khown that 44% are of a minority ace. 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 44% 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?

Question
Thirteen jurors are randomly selected from a population of 3 million residents. Of these 3 million residents, it is known that 44% 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 44% 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 44%, is (Round to four decimal places as needed.) (c) Choose the correct answer below. O A. The number of minorities on the jury is reasonable, given the composition of the population from which it came. B. The number of minorities on the jury is impossible, given the composition of the population from which it came. C. The number of minorities on the jury is unusually high, given the composition of the population from which it came. D. The number of minorities on the jury is unusually low, given the composition of the population from which it came.
