Extracted text: The random variable Y, with a density function given by my-1 f(y) = 0 < y=""><0, a,="" m=""> 0 is said to have a Weibull distribution. The Weibull density function provides a good model for the distribution of length of life for many mechanical devices and biological plants and animals. Find the mean and variance for a Weibull distributed random variable with m = 2.
