12 Explain why the following statement is true, or provide a counter-example: A receiver- operator characteristic curve, which plots the Type I error of a test against the Type II error from that same test, always slopes downward. See Figure 12.8(b) for an example of this kind of curve. a) Five possible thresholds FUR- & T3 TA B Type II error bad drugs (b) Receiver-operator characteristic (ROC) curve good drugs Ts T₁ T₂ T3 T₁ T Figure 12.8. Adjusting the rejection threshold creates a tradeoff between Type I error and Type II error. (a) Five possible thresholds. (b) Receiver-operator characteristic (ROC) curve.
