Twilve jurors are randomly selected from a population of 4 milion residents. Of these 4 milion residents, a is known that 45% are of a minority race. Of the 12 jurors selected, 2 are minorties. (a) What proportion of the jury described is from a minority race? (b) If 12 jurors are randomly selected from a population where 45% are minorities, what is the probability that 2 or fewer jurors will be minorities? (c) What might the lawyer of a defendant from this minonity race argue? (a) The proportion of the jury described that is from a minonity race is (Round to two decimal places as needed) (b) The probatality that 2 or fower out of 12 jurors are minorities, assuming that the proportion of the population that are minorites is 45%, is (Round to four decimal places as needed) (c) Choone the conect answer below OA The number of minonties on the jury is impossible, given the composition of the population from which it came. OB. The number of minorities on the jury is reasonable, gven the composition of the population from which it cane. OC The number of minonties on the jury is unusually high, given the composition of the population from which it came OD The number of minonties on the jury is unusually low, given the composition of the population from which it came

(b) If 12 jurors are randomly selected from a population where 45% 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 12 jurors are minorities, assuming that the proportion of the population that are minorities is 45%, 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. B. The number of minorities on the jury is reasonable, given the composition of the population from which it came. OC. The number of minorities on the jury is unusually high, given the composition of the population from which it came. D.

Suppose a life insurance company sells a $160,000 1-year term life insurance policy to a 20-year-old female for $320. According to the National Vital Statistics Report, 58(21), the probability that the female survives the year is 0.999544. Compute and interpret the expected value of this policy to the insurance company. The expected value is (Round to the nearest cent as needed.) Which of the following interpretations of the expected value is correct? Select the correct choice below and fill in the answer box to complete your choice. (Round to the nearest cent as needed.) O A. The insurance company expects to make a profit of $ on every 20-year-old female it insures for 1 month. O B. The insurance company expects to make a minimum profit of $ on every 20-year-old female it insures for 1 month. O C. The insurance company expects to make a profit of $ on every 20-year-old female it insures for 1 year. O D.
