Assume that the sensitivity and specificity of the new test for
alcohol use in items 12 to 16 remain unchanged. This time, however,
the gold standard is direct phlebotomy to measure blood alcohol
level, which shows there are actually 150 workers with detectable
blood alcohol rather than 20. The negative predictive value, given
the revised prevalence, is
a.1%
.b.35%
.c.67%
.d.12%
.e.98%.
