St. Broncoville Regional Medical Center is evaluating a new
rapid methicillin-resistant streptococcus aureus (MRSA) wound
culture test which can be performed in-house rather than sent out
to the reference laboratory in Capitol City. It takes three days
for the MRSA wound culture to return from the reference laboratory
(considered the gold standard) and costs $100. The new test kit
takes 24 hours to rule out MRSA and costs $50. The new rapid test
is 99.2% sensitive and 96% specific. The prevalence of wounds
infected with MRSA in your population is 2% per 10,000
persons.  Develop a 2 x 2 table.    

1. Calculate the Positive Predictive Value (PPV) for the new
test kit _____

2. Calculate the Negative Predictive Value (NPV) for the new
test kit _____

Enter only numbers into your answer. Round to two decimal places
after completing mathematical operations. Express your answer as a
percent but do NOT place a % sign after your answer.
