1) The probability that a vehicle will change lanes while making a turn is 62%. Suppose a random sample of 6 vehicles are observed making a turn at a busy intersection. a) Make a histogram showing the probability that r = 0, 1,2,3,4,5, 6 vehicles will make a lane change while turning. [6pts.] b) Find the expected value u of this probability distribution. (Round to the nearest hundredth) [3pts.] c) Find the standard deviation 0 of this probability distribution. (Round to the nearest hundredth) [3pts.]
