Anew screening test for lyme disease is developed for use in the general population. the sensitivity and specificity of the new test are 60% and 70%, respectively. three hundred people are screened at a clinic during the first year the new test is implemented. (assume the true prevalence of lyme disease among clinic attendees is 10%.) calculate the following values: the predictive value of a positive test is:

a. 33.0%
b. 18.2%
c. 94.0%
