In a binary decision problem, Neyman-Pearson criterion is used to decide which of two signals, one with amplitude A0=−2 and another with amplitude A1=3, is present in zero-mean Gaussian noise of variance σ 2 Z =5. The probability of false alarm, defined as deciding in favor of A1 when in fact A0 is present, is set to 25%. What is the probability of correct detection (deciding in favor of A1 when A1 is indeed present)? Express your answer in percentage and write it in the space provided below.数值题
