randomly chosen consecutive cars on a freeway during a period of heavy flow (sec). Suppose that in a particular traffic environment, the distribution of time headway has the following form. x> 1 x≤1 (a) Determine the value of k for which f(x) is a legitimate pdf. f(x) = x12 (b) Obtain the cumulative distribution function. F(x) = 0 x > 1 x ≤ 1 (c) Use the cdf from (b) to determine the probability that headway exceeds 2 sec. (Round your answer to four decimal places.) Use the cdf from (b) to determine the probability that headway is between 2 and sec. (Round your answer to four decimal places.) standard deviation (d) Obtain the mean value of headway and the standard deviation of headway. (Round your standard deviation to three decimal places.) mean (e) What is the probability that headway is within 1 standard deviation of the mean value? (Round your answer to three decimal places.)
