Suppose a company comes out with a test that is supposed to detect “mad cow” disease in cattle. The test is 95% accurate. What does that mean? (What is the numerical significance of 95%?)
The '95%' accurate part means that for every 100 cows they tested, 95 of them were found to have Mad Cow disease correctly. Like the fraction, [tex] \frac{95}{100} [/tex]
