Markov's inequality states that for any real-valued random variable Y and any positive number a, we have Pr( Y ≥a) ≤ E( Y )/a. One way to prove Chebyshev's inequality is to apply Markov's inequality to the random variable Y = (X − μ) with a = (kσ) : It can also be proved directly using conditional expectation: Chebyshev's inequality then follows by dividing by k σ . WebMay 31, 2024 · Using the Chebyshev’s inequality formula P( X − 120 < 10 × 3.16) ≥ 0.9 ⇒ P( X − 120 < 31.6) ≥ 0.9 ⇒ P( − 31.6 < X − 120 < 31.6) ≥ 0.9 ⇒ P( − 31.6 + 120 < X < 31.6 + 120) ≥ 0.9 ⇒ P(88.4 < X < 151.6) ≥ 0.9 Thus, the shortest interval (88.4, 151.6) will contain at least 90% of the daily production levels.
