Mark is reviewing a partial summary of results from a test data set on a small health clinic. With an accuracy 75% (100 count), Sensitivity 50%, and Specificity 100%, can Mark correctly predict the true positive rate to identify those with the flu?
A) Yes, because the specificity is 100% identifying healthy patients.
B) No, because the test set identified all patients with the flu.
C) No, because the sensitivity rate is only 50% in identifying those with the flu.
D) Yes, because there is a 75% accuracy rate with all healthy identified.
