1. The following table shows signal and noise distribution parameters (in nm) for two operators. State Operator 1 Standard Deviation 100 100 Mean 400 600 Noise Signal Mean 450 550 Operator 2 Standard Deviation 100 100 The industrial engineer who is responsible for signal detection task design, wants to see this operator's response change with respect to different payoff strategies on a ROC curve. Signal and noise values for the operator are distributed normally, and her criterion to call signal or noise changes with respect to presented payoff strategy as follows: Strategy V(H)>C(FA) V(H)=C(FA) V(H)C(FA) V(H)=C(FA) V(H)
