Answer 1

Given the table that shows the results of the test, you need to use the following in order to determine the sensitivity of the test:

`Sensitivity=(TP)/(TP+FN)`

Where TP is the number of true positives, and FN is the number of false negatives.

In this case, you can observe in the table that there are:

`\begin{gathered} TP=52 \\ FN=17 \end{gathered}`

Notice that there are 52 positives in the column "Has Condition". That is the number of True Positives. And there are 17 negatives in the same column, therefore, these are the number of False Negatives.

Then, substituting values into the formula and evaluating, you get:

`Sensitivity=(52)/(52+17)`
`\begin{gathered} Sensitivity=(52)/(69) \\ \\ Sensitivity\approx0.75 \end{gathered}`

Hence, the answer is:

`Sensitivity\approx0.75`
