Costas,
#24
Pr(9000-11000) = F(11000) - F(9000) = 0.05 by the F(x) fomula on Appendix.
With limit,
Pr(w/10000 limit AND claim size in range of 9000-11000)
= 0.25*Pr ( >9000) =0.25 * 0.148 say this to be P1
Pr ( claim size of range 9000 - 11000)
= 0.25*0 + 0.25*0.148 +0.5*0.05 = 0.25*0.248 say this to be P2
The answer will be P1/P2 = 0.148/0.248 = 0.597 Ans: C
#28
! mean integral and q mean lamda.
VHM = !(HM^2|q)g(q)dq - [ !(HM|q)g(q)dq]^2
HM|q = q
HM^2|q = 2q^2
!qg(q)dq = E(q) + 50
!q^2g(q)dq = 5000
VHM = 5000 - 50^2 = 2500 Ans: B
Good Luck,
Carrie
