Answer: 95.45%
Among the people who tested negative, there are 17 who have a condition and 357 who do not have a condition.
Since there are a total of 374 who tested negative, we can solve the percentage of the people who do not have the disease by dividing the number of people who do not have a condition by the total number of negative results.
[tex]\begin{gathered} P=\frac{\text{Does not have condition}}{\text{ Total number of negative results}} \\ P=\frac{357}{374} \\ P=0.9545\approx95.45\% \end{gathered}[/tex]
With this, we are 95.45% confident that the person does not have the disease.
