Question

under certain conditions the accuracy of a new blood test for screening high morality cancers is about 93%.

a. Assume that the prevalence of these types of cancers in the US is about 5% explain the meaning of a false negative with regard to this scenario.

b. for every 1,000 patients calculate the expected number of false positives in this scenario and compare it to the expected number of true positives.

Expert Solution

Step 1

here define events

person have cancer = C

test result is positive =T

here p(C) = 0.05

and under certain conditions the accuracy of a new blood test for screening high morality cancers is about 93%. that is 93% of the time test identifying result correctly
