Let X have a logistic distribution with pdf
Has a U(0, 1) distribution.
Answer to relevant QuestionsLet the random variable X be equal to the number of days that it takes a high-risk driver to have an accident. Assume that X has an exponential distribution. If P(X < 50) = 0.25, compute P(X > 100 | X > 50). If the moment-generating function of X is given by M(t) = e500t+5000t2, find P[27, 060 ≤ (X − 500)2 ≤ 50, 240]. The weekly gravel demand X (in tons) follows the Pdf However, the owner of the gravel pit can produce at most only 4 tons of gravel per week. Compute the expected value of the tons sold per week by the owner. Determine the indicated probabilities from the graph of the second cdf of X in Figure 3.4-4: (a) P (−1/2 ≤ X ≤ ½) . (b) P (1/2 < X< 1) . (c) P (3/4 < X < 2). (d) P(X > 1). (e) P(2 < X < 3). (f) P(2 < X ≤ 3). The joint pmf of X and Y is f(x, y) = 1/6, 0 ≤ x + y ≤ 2, where x and y are nonnegative integers. (a) Sketch the support of X and Y. (b) Record the marginal pmfs fX(x) and fY(y) in the “margins.” (c) Compute Cov(X, ...
