Question: Suppose you read a research article that suggests a 70 ms cutoff is potentially more appropriate than the 40 ms cutoff you used. You re-analyze your data and find that TP=17, FP=15, FN=24, and TN=44. Present the revised contingency table and calculate the new sensitivity, specificity, PV+, and PV-. Which cutoff (40 or 70 ms) appears to be more appropriate in terms of improving the diagnostic test? Explain.
