Tries remaining: Tries remaining: 5 f ( x ) = kxz if -1 5 x 54, 5 F (x ) = 1- if15x 2) = P ( 2 0.5) = (b) Find the expected value and median. (Round your answers to 4 decimal places, if needed.) E(X) = median = (c) Find the expected value and median. (Round your answers to 4 decimal places, if needed.) E(X) = median = (c) Find E(X2), the variance, and the standard deviation. (Round your answers to 4 decimal places, if needed.) E(X2) = (d) Find E(X2), the variance, and the standard deviation. (Round your answers to 4 decimal places, if needed.) E ( X2 ) = V(X ) = SD(X) = V(X ) = SD( X ) = Check
