Transcribed Image Text:28. Let X1, X2, and X3 represent the times necessary to
perform three successive repair tasks at a service
facility. Suppose they are independent, normal
rv's with expected values l1, µ2, and µ3 and var-
iances of, ož, and oz, respectively.
а. If
and of = o3 =
Hi = µ2 = µ3 = 60
o = 15, calculate P(X1 + X2 + X3 < 200).
What is P(150 < X1 + X2 + X3 < 200)?
b. Using the u;'s and o;'s given in part (a), calcu-
late P(55 < X) and P(58 < X < 62).
c. Using the u;'s and o;'s given in part (a), calcu-
late P(-10 < X -.5X2 — .5Xз < 5).
d. If M 3 40, 12 — 50, Из — 60, от — 10,
o3 = 12, and o = 14
X2 + X3 < 160) and P(X1 + X2 > 2X3).
