A new test has been developed to determine whether a given student is overstressed. It is known that 99.5% of all students are overstressed. This test is 95% correct if the student is not overstressed (i.e. conditional probability of the test indicating the student is not overstressed, when indeed he is not overstressed, is 0.95). This test is 85% correct if the student is in fact overstressed. Given that a particular student tests negative for stress (i.e. test shows that such student is not overstressed), choose the probability that the test results are correct (i.e. this student is indeed not overstressed) from the choices below?
