Negative Predictive Value
Sensitivity = TP / (TP + FN)
It measures a test's ability to correctly identify those who have the disease.
Specificity = TN / (TN + FP)
It measures a test's ability to correctly identify those without the disease.
Positive Predictive Value = TP / (TP + FP)
It measures a test's accuracy in diagnosing those with the disease. It is the chance that a person with a positive result actually has the disease.
Negative Predictive Value = TN / (TN + FN)
It measures a test's accuracy in diagnosing those without the disease. It is the chance that a person with a negative result is truly free of the disease.

Turtles with shells less than four inches were banned from sale. It was made to prevent Salmonella spread.

Well, I would be more specific in the role of the FDA. Their role is to protect consumers by regulation of foods and drugs which could be deemed harmful. Additionally, FSIS is specifically concerned with meat, poultry, and eggs, as it is part of the Dept. of Agriculture. Your turn.

I'm going to start this up again.

1. What is the ANOVA test?
2. In what situation would you use a t-test?
3. What causes Mad Cow Disease?
