If a woman takes an early pregnancy test, she will either test positive, meaning that the test says she is pregnant, or test negative, meaning that the test says she is not pregnant. Suppose that if a woman really is pregnant, there is 89% chance that she will test positive. Also, suppose that if a woman really is not pregnant, there is 97% chance that she will test negative. i) suppose that 900 women take early pregnancy tests and that 90 of them are pregnant. What is the probability that a randomly chosen from this group will test positive ? ii) suppose that 1000 women take early pregnancy tests and that 50 of them are pregnant. What is the probability that a randomly chosen from this group will test negative
