After performing and AB screen and detection, you suspect that the patient has and Anti-C. You counted 6 cells that had the C antigen that yielded an agglutination with the patient serum and 11 cells that did not have the C antigen that did not yield an agglutination. You tested 19 cells altogether. What is the p-value for the patient and is the identification valid based on the p-value?
