4.The results of a hypothetical study to measure test performance of the PCR (polymerase chain reaction) test for Covid-19 are shown in the following table.

Calculate the (A) accuracy, (B) precision (positive predictive rate, PPV), (C) recall (sensitivity, true positive rate, TPR), (D) true negative rate (TNR) and (E) F1-measure. Note: Show the result by rounding up the 3rd digit after the decimal point, e.g. 0.9876 should be 0.988.
3. Hamming code is a technique used to detect and correct errors in data transmission. It achieves this by adding specific check bits to the data bits. It enhances the reliability and stability of systems. After encoding with Hamming code, the value is 1101110101. Which bit is INCORRECT, and what is the CORRECT value?
2. Assume that there is a four-frame physical memory in the system. Initially, all frames are empty. Given the reference string: ACDFCBCADAFBAC, how many page faults generated by the LRU page replacement scheme? Show your work.
