QI. The choices for problem number 8 part b, from Section 7.3 in the book are given below.
* A. 6.9676
* B. 2.6396
* C. 4.5727
* D. 4.8776
* E. 8.0278
* F. None of the above.
* x___________I - 3 - 1 1 3 5
P(X = xj | 0.17 0.28 0.15 0.27 0.13
* Part B: Find the variance.
* E X = x 1 p.+ x2 p2 + x2 p2 = - 3 : 0 . 1 7 -11'0.28 1 0.15 + 3 '0.27' + 5' 0.131 = 0.82 = p
* Vor A’ = p. x x — | Z + p 2l x, - p 2+ p2
= 0.17(-3 - 0.82) 2 + 0.28(-l - 0.82) 2 + 0.15(1 - 0.82) + 0.27(3 - 0.82) 2 + 0.13(5 - 0.82) 2
= 6.9676
Q2. The choices for problem number 10 pan b, from Section 7.3 in die book are given belowT
.
* A. 312.4215
* B. 284.8275
* C. 248.9658
* D. 298.9746
* E. 315.9872
* F. None of the above.
* x | 0 15 30 45 60
P(A' = x) | 0.24 0.46 0.13 0.11 0.06
* Part B: Find die variance.
* E A" =x1 p + x2 p2 + x2 pt
= 0(0.24) + 15(0.46) + 30(0.13) + 45(0.11) + 60(0.06) = 19.35 = p
Vor A =p. x x —p) 2-pj.x 2 - p ' + p; x3 “ p ?
= 0.24(0 - 19.35) 2 + 0.46(15 - 19.35) 2 + 0.13(30 - 19.35) 2 + 0.11(45 - 19.35) 2 + 0.06(60 - 19.35) 2
= 284.8275
