Answer:
P(POSc/Sc)
Step-by-step explanation:
As,
POS= Test has positive results
and
S=Adult has tuberculosis.
The test correctly identifies 74.6% of the time adults with a tuberculosis and correctly identifies those without tuberculosis 76.53% of the time.
In the above statement 76.53% describes the probability of adult who don't have tuberculosis gets the negative results as test is correctly identifying.
So, getting negative results means that not positive results and for this event the notation of complement POSc is used. Also, not having tuberculosis can be denoted as Sc. So,
POSc= Test has negative results
Sc=Adult hasn't tuberculosis
Thus, P(POSc/Sc) depicts the probability of adults not having tuberculosis gets correct results.
Hence, P(POSc/Sc)=76.53%
Answer: D) how close a measured value is to the actual value.
Step-by-step explanation: Accuracy is simply a measurement metric which is used to establish how a measured or predicted value conforms to the actual measurement usually in terms of closeness. Accuracy is different from precision which measures closeness in values obtained from repeated measurement of the same sample. For instance;
If the actual vale of a measurement is : 11.34
Prediction 1 : 11.30
Prediction 2 : 11.32 ;
Prediction 2 will be said to be more accurate than prediction 1 becuase it is closer to the actual value than prediction 1.
