A methods and measurements analyst for Digital Devices needs to develop a time standard for the task of assembling a computer mouse. In a preliminary study, she observed one of her workers perform this task six times with the following results: $$\begin{array} { l r r r r r r }
\text { Observation } & 1 & 2 & 3 & 4 & 5 & 6 \
\hline \text { Time (seconds) } & 46 & 38 & 40 & 34 & 42 & 40
\end{array}$$ What is the observed time for this task?
A) 34 seconds
B) 40 seconds
C) 46 seconds
D) 48 seconds
E) 240 seconds

Quizplus · Accepted Answer

The observed time for the task of assembling a computer mouse is found by taking the average of the times recorded in the preliminary study.

Observed time = (46 + 38 + 40 + 34 + 42 + 40) / 6 = 40 seconds

Therefore, the best choice is B, as it is the observed time calculated from the data provided.
