Automobiles arrive at a vehicle equipment inspection station according to a poisson process with rate α = 8 per hour. suppose that with probability 0.5 an arriving vehicle will have no equipment violations.
(a) what is the probability that exactly eight arrive during the hour and all eight have no violations? (round your answer to four decimal places.)
(b) for any fixed y ≥ 8, what is the probability that y arrive during the hour, of which eight have no violations?
(c) what is the probability that eight "no-violation" cars arrive during the next hour? [hint: sum the probabilities in part (b) from y = 8 to [infinity].] (round your answer to three decimal places.)

Data from 2005 for various age groups show that for each $100 increase in the median weekly income for whites, the median weekly income of blacks increases by $105. also, for workers of ages 25 to 54 the median weekly income for whites was $676 and for blacks was $527. (a) let w represent the median weekly income for whites and b the median weekly income for blacks, and write the equation of the line that gives b as a linear function of w. b = (b) when the median weekly income for whites is $760, what does the equation in (a) predict for the median weekly income for blacks?
