We are screening 200 college students for Caffeine-itis, a condition caused by the intake of too much caffeine during exam periods.

Of those positive results, 30 samples were false positives. We know that there are 100 students with confirmed Caffeine-itis based on diagnostic testing performed by a physician. Calculate the specificity and sensitivity of the test as well as the predictive values (positive and negative) for the data.
