Question: Find standard deviation X P(x) X*P(X) (x - H) 2P(x) 2 0.1 2(0.1) = 0.2 (2-5.4)2(0.1) = 1.156 4 0.3 4(0.3) = 1.2 (4 5.4)2(0.3)

Find standard deviation

X P(x) X*P(X) (x - H) 2P(x) 2 0.1 2(0.1) = 0.2 (2-5.4)2(0.1) = 1.156 4 0.3 4(0.3) = 1.2 (4 5.4)2(0.3) = 0.588 6 0.4 6(0.4) = 2.4 (6 5.4)2(0.4) = 0.144 8 0.2 8(0.2) = 1.6 (8 5.4)2(0.2) = 1.352 Table 4.24
