Can somebody show me how to find the median and variance of this piece wise function? I've been trying so hard to do it. f(x) = 4/(x^5) , x >= 1 0, otherwise Ans: 1.11, 7/9

Hello, Compute the cdf : F(t)=0 if t<1 if t>1 The median is the value m such that . Shouldn't be too difficult... The variance is Note : the fact that it is piecewise is not that important. Here, it just tells you the range of the distribution.
