= P (Z > 3σw / (1.5σw2)1/2) + P (Z < 3σw / (1.5σw2)1/2)
= P (Z > 2.45) + P (Z < 2.45) = 2(0.0072) = 0.014
No.
(c) P( E + µw + 2σw > µw + 3σw) = P(E > σw) = P(Z > σw/(0.5σw2)1/2)
= P(Z > 1.41) = 0.079
Also, P( E + µw + 2σw < µw – 3σw) = P( E < – 5σw)
= P(Z < 5σw/(0.5σw2)1/2) = P(Z < 7.07) ≈ 0 566 D=ABC
