Sally came for the test, and she tested negative for diabetic. Do you think Sally should go for a second opinion? How will Sally be affected if only 3% of the population has diabetic? Explain the findings. n. ii. If Sally was tested positive for the test, what is the probability that she has diabetic? Explain the findings.
