Another way of pricing the food consumed is to use the number and color of the dishes left on the patron's table as a guide, similar to the method used in some Japanese conveyor belt sushi restaurants. Some newer restaurants offer a conveyor belt dim sum format, similar to the conveyor belt sushi eating places.
Sensitivity refers to a test's ability to designate an individual with disease as positive. A highly sensitive test means that there are few false negative results, and thus fewer cases of disease are missed. The specificity of a test is its ability to designate an individual who does not have a disease as negative. A highly specific test means that there are few false positive results.
Sensitivity is the ability of a test to correctly identify individuals who have a given disease or condition. For example, a certain test may have proven to be 90% sensitive. If 100 people are known to have a certain disease, the test that identifies that disease will correctly do so for 90 of those 100 cases (90%).The other 10 people (10%) tested will not show the expected result for this test. For that 10%, the finding of a normal result can be misleading and is termed false-negative.or example, a certain test may have proven to be 90% sensitive. If 100 people are known to have a certain disease, the test that identifies that disease will correctly do so for 90 of those 100 cases (90%).
