​The information obtained by comparing a new diagnostic test with the gold standard is summarized in a two-by-two table given below​

​What is the sensitivity and specificity of the new test?​

Correct option is C

Explanation-

To find the sensitivity and specificity:

​$$\text{Sensitivity} = \frac{\text{True Positives}}{\text{True Positives} + \text{False Negatives}}$$

$$\text{Specificity} = \frac{\text{True Negatives}}{\text{True Negatives} + \text{False Positives}}$$

From the table:
 True Positives (TP) = 68
 False Negatives (FN) = 32
 True Negatives (TN) = 78
 False Positives (FP) = 22
Calculations:​​​

​$$\text{Sensitivity} = \frac{68}{68 + 32} = \frac{68}{100} = 68\%$$

$$\text{Specificity} = \frac{78}{78 + 22} = \frac{78}{100} = 78\%$$

So, the correct answer is Option C - Sensitivity = 68%, Specificity = 78%
