In the paper about a baby of the author's colleague, the heel stick blood test for creatinine phosphokinase (CPK) was used as a diagnostic test for multiple schlerosis in infants.

The test had seemingly amazing characteristics. Suppose that the sensitivity of the test is 1.00, and the specificity of the test is 0.9998. We suppose that the prevalence of muscular distrophy among infants is 0.0002 (1 in 5000). Please give all answers to 4 decimal places.

What is the probability of a false negative test (the probability that a person having muscular distrophy tests negative)?
