Understanding Karim's Cholesterol Test Method

Karim developed a non-invasive method to measure cholesterol levels, aiming for 99% accuracy. Initial tests showed 95% accuracy compared to blood tests. To validate his method, Karim conducted 100 computer simulations assuming 99% accuracy. The simulations showed a low probability of achieving only 95% accuracy, suggesting his method might not meet the 99% standard. The analysis led to questioning the hypothesis that the test is 99% accurate.
