Answer:
0.0392 = 3.92% probability that the test result is positive.
Step-by-step explanation:
Probability of a positive test:
95% of 1%(person has the disease)
100 - 97 = 3% of 100 - 1 = 99%(person does not have the disease).
What is the probability that the test result is positive?
[tex]p = 0.95*0.01 + 0.03*0.99 = 0.0392[/tex]
0.0392 = 3.92% probability that the test result is positive.
