Multiple Choice

A worker was observed for four cycles in a repetitive task that contains four distinct elements. The observer recorded the following items in seconds, using the continuous method.
$$\begin{array} { | c | c | c | c | c | } \hline \text { Element } & \text { Cycle 1 } & \text { Cycle 2 } & \text { Cycle3 } & \text { Cycle4 } \\\hline \mathbf { 1 } & 12 & 66 & 111 & 168 \\\hline \mathbf { 2 } & 21 & 75 & 122 & 185 \\\hline \mathbf { 3 } & 37 & 86 & 133 & 200 \\\hline \mathbf { 4 } & 53 & 89 & 146 & 209 \\\hline\end{array}$$
