Clinical data for testing of one rapid-response screening test for the flu is shown in the table below. A positive test result provides evidence that the person has the flu and a negative test result provides evidence that the person does not have the flu. results of screening test positive negative total actually has flu does not have flu total 42 11 53 43 204 247 85 215 300.
how many false positives were there? what does this mean?
determine the sensitivity of the test. what does this indicate about the test?
determine the specificity of the test. what does this indicate about the test? determine the negative predictive value of the test.
determine the positive predictive value of the test.

understand that i don't know the answers

will someone answer his question

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough

correct answer was 0.5
