1) Suppose you have invented a medical system that predicts a certain disease. The machine only predicts two types of result: POSITIVE and NEGATIVE. You ran the system on 1,000 patients and collected 1,000 system predictions. Now, assume you happen to know the right answer of each patient on whether he or she has the disease (we refer to the right answer "ground truth" or "gold standard"). You recorded both the ground truth and system predictions onto one single file. (2) Import the data file "lab_tests.txt". First column represents ground truth, while the second column represents system's prediction. You need to create two list variables, gold and predict, to store these values. Each list contains 1,000 items. Need help importing data? See the following code for reference
