Web1. Comparing the given equation with Chebyshev's inequality, we get μ = 1. Since X here has X 1 and X 2 i.i.d. continuous random variables, so both have same pdf and E [ X] = E [ X 1] + E [ X 2] The mistake I did was to not calculate both X 1 and X 2 separately. So the calculated E [ X] is actually E [ X 1] = 1 2 and similarly E [ X 2] = 1 2.

WebFeb 3, 2024 · Solution. Here we use Chebyshev’s inequality and work backward. We want 50% = 0.50 = 1/2 = 1 – 1/ K2. The goal is to use algebra to solve for K . We see that 1/2 = 1/ K2. Cross multiply and see that 2 = K2. We take the square root of both sides, and since K is a number of standard deviations, we ignore the negative solution to the equation.
