A new test is developed to detect a certain allergy, giving "positive" or "negative" results to indicate whether a person has the allergy.
- For a person who has the allergy, the test will give a positive result 82% of the time and a negative result (false negative) 18% of the time.
- For a person who does not have the allergy, the test will give a positive result (false positive) 10% of the time and a negative result 90% of the time.
A study included a population of 10,000 people, and 1% of those studied were known to have the allergy.
Fill in the missing values in the table below and complete the statements that follow. Round the percentages to the nearest tenth, if necessary.

\begin{tabular}{|c|c|c|c|}
\hline & \text{Number of People} & \text{Positive Test} & \text{Negative Test} \\
\hline \text{Have Allergy} & 100 & \square & 18 \\
\hline \text{Don't Have Allergy} & 9900 & 990 & \square \\

\end{tabular}

If an individual's test gives a positive result, it is \square\% likely that the person has the allergy.
Therefore, this test \square (should/should not) be used for allergy testing.
