Random Variables : Probability, Mean and Variance

Let the continuous r.v.X denote the weight (in pounds) of a package. The range of weight of the package is between 45 and 60 pounds. (a) Determine the probability that a package weighs more than 50 pounds. (b) Find the mean and the variance of the weight of packages. HINT: Assume that X is uniformly distributed over (45 ...continues

Random Variables : Median and Mode

The median of a continuous r.v. X is the value of X = Xo such that P(X> or = Xo) = P(X , or = Xo) the mode of X is the value of x = xm at which the pdf of X achieves its maximum value. (a) Find the median and mode of an exponential r.v. X with parameter lambda. (b) Find the median and mode of a normal r.v. X = N ( mu, sigm ...continues

Random Variables : Probability Mass Function, Mean and Variance

A lot consisting of 100 fuses is inspected by the following procedure: 5 fuses are selected randomly, and if all 5 "blow" at the specified amperage, the lot is accepted. Suppose that the lot contains 10 defective fuses. Find the probabily of accepting the lot. HINT: Let X ba a r.v. equil to the number of defective fuses in ...continues

Laplace Random Variables : Cumulative Distribution Function, Mean and Variance

A r.v. X is called a Laplace r.v. if its pdf is given by fx(x) = ke ^(-lambda |x|) lambda>0, -infidenity< x < infidenty where k is a constant. (a) Find the value of k. (b) Find the cdf of X. (c) Find the mean and the variance of X.
