Question

Code Churn is a common metric used to measure the efficiency and productivity of software engineers and computer programmers. It's usually measured as the percentage of a programmer's code that must be edited over a short period of time. Programmers with higher rates of code chum must rewrite code more often because of errors and inefficient programming techniques. The following table displays sample information for 10 computer programmers. DATA Total Lines of Code Programmer Written Number of Lines of Code Requiring Edits Liwel 23,789 4,589 Andrew 17,962 2,780 Jaime 31,025 12,080 Sherae 26,050 3,780 Binny 19,586 1,890 Roger 24,786 4,005 Dong-Gil 24,030 5,785 Alex 14,780 1,052 Vivek 30,875 3,872 21,546 4,125 Probability 0.1929 0.1547 0.3893 0.1451 0.0964 0.1615 0.2407 0.0711 0.1254 0.1914 Round your answers to four decimal places. b.
