Question

The accompanying table displays results from experiments with polygraph instruments. Find P(subject told the truth | negative test result). Find P(negative test result | subject told the truth). Compare the results from parts a. and b. Are they equal? Click the icon to view the data table. P(subject told the truth | negative test result) = [ (Round to three decimal places as needed.) Find the probability of selecting a subject with a negative test result, given that the subject told the truth. P(negative test result | subject told the truth) = [ (Round to three decimal places as needed.) Compare the two values. Are they equal?

Explanation / Answer

Answer to the question)

Since there is no data provided in the question

the formulae that can help answer these questions are as follows

part a)

P(subject told truth | negative test result) = P(subject told truth AND negative result ) / P(negative result)

.

Part b)

P(negative test result | subject told truth) = P(subject todl truth AND negative result ) / P(Subject told truth)

.

Part c)

The results for part a and b cannot be equal , because the denominator value in both the formulae is different
