[Calvin tries to call Hobbes]
Calvin is trying to call Hobbes but he doesn't know if the number he's calling is his home phone or his work phone. The probability that Hobbes answers at his home phone is p0, whereas the probability that Hobbes answers at his work phone is p1, with xxGeometric(pi)Hi20=31H1pMD,pFApep0=e-1,p1=1-e-1H1p0p1pMD,pFApep0=e-1,p1=1-e-10. Calvin calls the number he has once a day until Hobbes finally picks up. Let x denote the number of times Calvin has to call up until Hobbes finally answers (the answered call included in the count). Assume that the successive call attempts are independent trials ofan experiment, so that xGeometric(pi), under hypothesis Hi. Assume that 20=31.
(a) Obtain the ML decision rule. Assume ties are broken in favor ofH1.
(b) Obtain pMD,pFA, and pe under the ML decision rule assuming p0=e-1,p1=1-e-1.
(c) Obtain the MAP decision rule. Assume ties are broken in favor ofH1, and leave p0 and p1as variables (do not use the values given in part (b)).
(d) Obtain pMD,pFA, and pe under the MAP decision rule assuming p0=e-1,p1=1-e-1.
