Question

Survey showed that the probablity that an e

claimed that he could help place any employee in
id in a job that Is sultable for the employee Is 0.65. A psychometric test consultant
company decides to take this test. The test has an a
based on the result of a psychometric test. An employee working in a particular
rate of 70%. This data is represented in the tree diagram.
fest predicts that
the employee is in
probability that
the employee

the employee is in
the wrong job
Select the correct answer.
Which of these probability values fit the tree diagram?
RA) = 0.35, P(6) = 0.65, RQ) = 0.70, P(O) = 0.30, P(E) = 0.30, P(A) = 0.70
O B. PA) = 0.35, P(6) = 0.65, A(Q) = 0.70, R,D) = 0.30, A8) = 0.70, RA = 0.30
O c.
14) = 0.35, P(6) = 0.65, PQ) = 0.30, P(O) = 0.70, RJ8) = 0.70, AA = 0.30
= 0.30, PA = 0.70

Answer 1

A survey shows that the probability that an employee gets placed in a suitable job is 0.65. So, the probability he is in the wrong job is 0.35.The test has an accuracy rate of 70%. So, the probability that the test is inaccurate is 0.3. Thus, the probability that someone is in the right job and the test predicts it wrong is The probability that someone is in the wrong job and the test is right is
