Essay

The data in the following table represent time-study observations on a new operation with three work elements. On the basis of these observations, find the standard time for the process. Assume an 8% allowance factor. $$\begin{array} { | c | c | c | c | c | c | } \hline & & { \text { Observations(times in seconds) } } \\\hline \text { Element } & \text { Performance Rating } & 1 & 2 & 3 & 4 \\\hline 1 & 105 \% & 110.2 & 110.8 & 112.3 & 108.7 \\\hline 2 & 90 \% & 114.7 & 115.7 & 114.8 & 114.2 \\\hline 3 & 115 \% & 109.2 & 109.3 & 109.2 & 108.9 \\\hline\end{array}$$
