4. For any random variable X with mean ,u and standard deviation 0, Chebyshev's inequality states that 1 FOX'1' 2kg)SFa A Where k is some real number. Suppose 5 is an unbiased estimator of 0 with standard error 0(0). (For example if 9': X, then 0(X) = i.) Use Chebyshev's inequality to construct a condence interval which has at least 95% coverage probability
