The sensitivity of the test is 0.9
Step-by-step explanation:
The given information are;
Has disease, Does not have disease
Test positive, 180 40
Test negative, 29 400
Where:
True Positive = TP = 180
False Positive = FP = 40
False Negative = FN = 29
True Negative = TN = 400
Sensitivity = TP/(TP + FN) = 180/(180 + 29) = 0.861
The sensitivity for the test is 0.861 which is 0.9 to one decimal place.
