Question
Let the variable X be someone's disease status
- X = D then someone has strep throat
- X = Dc then someone does not have strep throat
Let the variable Y be someone's test result
- Y= + is a positive test indicating the test detected strep throat
- Y = - is a negative test indicating the test did not detect strep throat
Y=+ | Y=- | |
X=D | 36 | 17 |
X=Dc | 13 | 20 |
1. Calculate the probability that someone who is known to not have strep throat will get a negative test result
I've been told 0.5405 and 0.6061 as possinle answers.
2. Calculate the Specificity of the test
Round your answer to 4 decimal places.
