We are screening 200 college students for Caffeine-itis, a condition caused by the intake of too much caffeine during exam periods. Our new screening test assesses the amount of caffeine in the urine. At the time of screening, the test determined that there were 110 samples positive for caffeine. 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.
