The document discusses a continuous random variable z characterized by the probability density function f(z)=2z for the range 0 to 1. It prompts the calculation of the coefficient of variation for this variable. The coefficient of variation provides a standardized measure of the dispersion of the random variable.

1. Consider a continuous random variable Z with probability density function given by f(z)=2z for 0z1
. Calculate the coefficient of variation for Z.
