9. A simple and inexpensive screening method has been developed to identify individuals with HIV infection at routine medical check-ups. To study the sensitivity and specificity, the method was tested on 1860 persons who underwent a simultaneous and thorough clinical examination that was considered to give an accurate diagnosis.

The results were as follows:
The clinical test identified 1160 individuals as having the disease, whereas the screening method identified 480 as being positive for the disease. The screening method correctly identified 160 among those with clinical disease.

Calculate the sensitivity of the screening method and specificity of the screening method.
