12. let θ denote the proportion of registered voters in a large city who are in favor of a certain proposition. suppose that the value of θ is unknown, and two statisticians a and b assign to θ the following different prior p. d.f.’s ξa(θ ) and ξb(θ ), respectively: ξa(θ ) = 2θ for 0 < θ< 1, ξb(θ ) = 4θ 3 for 0 < θ< 1. in a random sample of 1000 registered voters from the city, it is found that 710 are in favor of the proposition. a. find the posterior distribution that each statistician assigns to θ. b. find the bayes estimate for each statistician based on the squared error loss function. c. show that after the opinions of the 1000 registered voters in the random sample had been obtained, th

The school track has eight lanes. each lane is 1.25 meters wide. the arc at each end of the track is 180. the distance of the home straight and the radii for the arcs in the 1st 4 lanes are given. s=85m r1=36.5m r2=37.75m r3=39m r4=40.25m part one: find the radii of lanes 5 through 8 of the track. show your work. part two: if max ran around lane one, how far did he run? show your work and explain your solution. part three: max wants to run a total of three laps around the track, choose two additional lanes (2-8) for him to run and find the distance around those two lanes. show your work and round to the hundredths. part 4: based on your lane choices in part three, what was the total distance max ran in the three laps around the track?
