The answer posted didn't use the given AC values.

The following data have been collected for a British health care IT project for two-week reporting perlods 2 through 12 . Compute the SV, CV, SPI, CPI, and PCIB for each perlod. (Do not round intermedlate calculations. Enter all values to 2 decimal precision. For SPI, CPI, and PCI-B, enter in decimals rather than percentage format. (i.e., enter 0.93 if the answer is 93% )) \begin{tabular}{|c|c|c|c|c|c|c|} \hline End of Period 6 & & & & & \\ \hline Task & Actual \% Complete & EV & AC & PV & CV & SV \\ \hline 1 & 100 & & 9.00 & & \\ \hline 2 & 20 & & 15.00 & & \\ \hline 3 & 30 & & 11.00 & & \\ \hline 4 & 0 & & 0.00 & & \\ \hline Cumulative Totals & & & & \\ \hline \end{tabular} \begin{tabular}{|c|c|c|c|c|c|c|} \hline End of Period 8 & & & & & \\ \hline Task & Actual \% Complete & EV & AC & PV & CV & SV \\ \hline 1 & 100 & & 9.00 & & \\ \hline 2 & 30 & & 18.00 & & \\ \hline 3 & 70 & & 20.00 & & \\ \hline 4 & 0 & & 0.00 & & \\ \hline Cumulative Totals & & & & \\ \hline \end{tabular} \begin{tabular}{|c|c|c|c|c|c|c|} \hline End of Period 12 & & & & & \\ \hline Task & Actual \% Complete & EV & AC & PV & CV & \\ \hline 1 & 100 & & 9.00 & & \\ \hline 2 & 100 & & 50.00 & \\ \hline 3 & 100 & & 40.00 & \\ \hline 4 & 100 & & 40.00 & & \\ \hline 5 & 50 & & 30.00 & & \\ \hline 6 & 60 & 30.00 & 40.00 & 40.00 & (4.00) & (4.00) \\ \hline Cumulative Totals & & & & \\ \hline \end{tabular} \begin{tabular}{|c|c|c|c|c|c|c|} \hline Performance Indexes Summary & & & & \\ \hline Period & EV & AC & PV & SPI & CPI & PCI-B \\ \hline 2 & & & & & & \\ \hline 4 & & & & & & \\ \hline 6 & & & & & & \\ \hline 8 & & & & & & \\ \hline 10 & & & & & & \\ \hline 12 & & & & & & \\ \hline \end{tabular} EACf=VACf=
