An initial analysis of a laboratory activity resulted in the first table below. After this analysis, the managers determined that their element descriptions were not as accurate as they should have been-they had left out an element, underestimated a distance, and understated the need for accuracy. They revised the table of element data, which appears in the second table. $\text { Original Activity: Pouring tube specimen }$ $\begin{array}{|l|c|c|} \hline\text { Element description } & \text { Element code } & \underline{\text { TMU }} \\ \hline \text { Get tube from rack } & \mathrm{AA} 2 & 35 \\ \hline \text { Get stopper, place on counter } & \mathrm{AA} 2 & 35 \\ \hline \text { Get centrifuge, place at sample } & & \\ \text { tube } & \mathrm{AD} 2 & 45 \\ \hline \text { Pour }(3 \mathrm{sec} \text {.) } & \mathrm{PT} & 83 \\ \hline \text { Place tubes in rack (simo) } & \mathrm{PC} 2 & 40 \\ \hline \text { TOTAL TMU } & &\\ \hline \end{array}$ $\text { Revised Activity: Pouring tube specimen }$ $\begin{array}{|l|c|c|} \hline\text { Element description }& \text { Element code } & \text { TMU } \\ \hline \text { Get tube from rack } & \mathrm{AC} 3 & 70 \\ \hline \text { Get stopper, place on counter } & \mathrm{AA} 2 & 35 \\ \hline \text { Get centrifuge, place at sample } & & \\ \text { tube } & \mathrm{AD} 2 & 45 \\ \hline \text { Pour (3 sec.) } & \mathrm{PT} & 83 \\ \hline \text { Get stopper, place on tube } & \mathrm{AC} 1 & 40 \\ \hline \text { Place tubes in rack (simo) } & \mathrm{PC} 2 & \underline{40} \\ \hline \text { TOTAL TMU } & &\\ \hline \end{array}$ Calculate the total standard minutes for the original activity "pouring tube specimen."
