Given the following results Sample ID Predicted Value Sample Label 1 0.9 1 2 0.8 1 3 0.5 1 4 0.6 0 5 0.4 0 (a) (10 Pts) Using 0.5 as a cutoff, namely >=0.5 then predict the sample as 1, and 0 otherwise. Please compute true positive rate and the false positive rate. (b) (10 Pts) please compute its AUC manually
