Question

Health officials are monitoring a screening program from STD testing at a facility. For a one-month period 220 individuals have been tested for a particular STD. 60 people tested positive and 160 people tested negative. Of the 60 people who tested positive, 8 truly did not have the disease (false positive). Of the 160 who tested negative, 150 truly did not have the disease. What would the positive predictive value be for this test?a. 8 / 52 + 8 = 13%
b. 52 / 52 + 10 = 84%
c. 52 /52 + 8 = 87%
d. 150 / 150 + 10 = 94%
e. 150 / 150 + 8 = 95%

Answer 1

Answer:

The positive predictive value for this test would be  (c) 52 /52 + 8 = 87%

Explanation:

step 1; you subtract the false positive from the from the real positive in the test which is given by; 60-8= 52.

Step 2: to find the actual number of positive predictive value for this test we divide the number actual positive by the number of supposed total positive and multiply by 100%. i.e $\frac{52}{60}$ X 100%= 86.6% approximately = 87%
