most computer languages include a function that can be used to Generate random numbers in Excel the Rand function can be used to Generate random numbers between 0 and 1 if we let X denote a random number General using R and then X is a continuous random variable with the following probability density function
Use Excel to generate 70 values from Normal distribution with mean 18 and standard deviation 5. Construct a histogram for them [Note: first generate 100 uniformly distributed random values from [0,1]; then use them as the first input for NORMINV( ) function, two other inputs are mean and standard deviation of given Normal distribution. can you show me step by step how to do this in excel
Let F be a continuous distribution function and let U be a uniform (0, 1) random variable (a) If X F-(U), show that X has distribution function F. Show that -log(U) is an exponential random variable with mean 1.
Let X be an uniform distribution between 0 and 1, Y be an uniform distribution between -5 and 3, and they are independent. Calculate the pdf, expectation, and the variance of the followings 1. 4X

Instructions: If you require uniformly distributed random
numbers
in [0, 1], use Matlab’s built in uniform random number generator
rand. Also,
you may NOT use any Matlab built-in functions that explicitly
perform the task
asked for in the problem.
Problem 6. Let α > 0 and set f(x)- ae-ale, for x e(-oo, oo). (a) Make a plot of f (b) Show that f is a probability density function (Hint: -, when z S 0, and x-r, when 0.) (c) If...
Suppose that you need to generate a random variable Y with a density function f (y) corresponding to a beta distribution with range [0,1], and with a non-integer shape parameter for the beta distribution. For this case there is no closed-form cdf or inverse cdf. Suppose your choices for generating Y are either: a) an acceptance-rejection strategy with a constant majorizing function g(u) = V over [0, 1], i.e., generate u1 and u2 IID from a U[0,1] generator and accept...
Say I want to generate random variables from the probability distribution p={ 2-2x 0<x<1 0 . elsewhere My scheme is to generate U's from [0,1],double them and plug them into the probability distribution. So U = 0.3 gives me p(0.6)=0.8 as random variable. Prove my idea is right or wrong.
4.60 The sum of two uniform random numbers. Generate two random numbers between 0 and 1 and take Y to be their sum. Then Y is a continuous random variable that can take any value between 0 and 2. The density curve of Y is the triangle shown in Figure 4.12. (a) Verify by geometry that the area under this curve is 1. (b) What is the probability that Y is less than 1? [Sketch the density curve, shade the...
