Tests for tuberculosis like all other diagnostic tests are not perfect. qft-g is one of such tests for tuberculosis. suppose that for the population of adults that is taking the test, 5% have tuberculosis. the test correctly identifies 74.6% of the time adults with a tuberculosis and correctly identifies those without tuberculosis 76.53% of the time. suppose that pos stands for the test gives a positive result and s means that the adult really has tuberculosis. what is the probability of an adult getting a pos result and truly not having tuberculosis?

The probability of having a positive test on a non-sick person is 24.32%.

Step-by-step explanation:

The probability of having a POS and not having tuberculosis, can be defined as the probability of getting a false positive.

The amount of positive test will be

1) The positive test of sick persons

2) The positive test of not-sick persons (false positives)

The amount of positive test will be

1) The negative test of non-sick persons

2) The negative test of sick persons (false negatives)

the probability is 0

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
