Assume that x is a uniformly distributed random number between 0 and 1 (e.g. x is the RAND() function in Excel), and that the number of units to be sold is uniformly distributed between 100 and 400. In this case, sales are given by the expression:
400 - 100 * x
100 + 400 * x
400 + x
300 + / - x

Problem 2. Suppose that a uniformly distributed random number X in [0, 1] is found by calling a random number generator. Then, if the call to the RNG produces the value r for X, another random number Y is computed that is uniformly distributed on (0, x). That is, X is uniform on the interval [0, 1], and the conditional distribution for Y given X -a is uniform on the interval [0,x] a) Calculate E(Y X-0.4). b) Calculate E (X...

Many random number generators allow users to specify the range of the random numbers to be produced. Suppose that you specify that the range is to be all numbers between 0 and 5. Call the random number generated Y. Then the density curve of the random variable Y has constant height between 0 and 5, and height 0 elsewhere. 1. Use Excel to generate 100 random values from the above distribution. Construct a histogram for generated values [ Note: use...

Let X be a uniformly distributed random variable on [0,1]. Then, X divides [0,1] into the subintervals [0,X] and [x,1]. By symmetry, each subinterval has a mean length 0.5. Now pick one of the subintervals at random in the following way: Let Y be independent of X and uniformly distributed on [0,1], and pick the subinterval [0,X], or (X,1] that Y falls in. Let L be the length of the subinterval so chosen. What is the mean length of L...
