Answer 1

26. It tells you the probability that a test reflects a person who has the disease.

27. It increases or decreases in relation to the specificity of your test.

29. It tells you the probability that a negative test result reflects a person who does not have the disease.

Sensitivity - is the probability that tell the diseased individual.

Sensitivity = true positives/ (true positive + false negative).

Specificity - is the probability that tell the population that diseased is not formed.

Specificity = true negatives/ (true negative + false positive).
