3. The population mean of X is the probability weighted value of X:

= (9*.2 + 17*.2 + 24*.5 + 36*.1)

= 20.8

4. The deviation is 7.68 . It is found out in the following way:

p(x) x^2 E(x^2) Var(x) = E(x^2) - E(x)^2 Stdev(x) = sqrt(Var(x)) 58.96 7.68 20.80 491.6 E(x) 0.2 0.2 0.51 0.1 81 289 576 1296
