A Pareto distribution is often used in economics to explain a distribution of wealth. Let a random variable X have a Pareto distribution with parameter θ so that its probability distribution function is for and 0 otherwise. The parameters and are known and fixed; is a constant to be determined. a) Assuming that find the expected value and variance of ? b) Show that for 3 ≥ θ > 2 the Pareto distribution has a finite mean but infinite variance,...

Find mean and variance of binomial distribution, i.e. if probability density function is:
. km m2k 1. Please show that the mean is * k > 1, and variance is k-1 (k-1)2(k-2)' for Pareto distribution. Please also show that the Pareto distribution approaches δ(x-m) as k → 00,
A distribution has a mean of 12 and a variance of 250. Find the second moment about the origin.
1. Using calculus, find the mean and variance of a uniform distribution with a minimum value of of O and a maximum value of 10. (Give a proof.) Remember that the variance can be calculated using: < X z >-< X >2.
