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: $$\begin{array} { | l | c | c | c | c | c | c | }
\hline \text { Observation } & 1 & 2 & 3 & 4 & 5 & 6 \
\hline \text { Time(Seconds) } & 46 & 38 & 40 & 34 & 42 & 40 \
\hline
\end{array}$$ What is the observed time for this task?
A) 34 seconds
B) 40 seconds
C) 46 seconds
D) 48 seconds
E) 240 seconds

A) 34 seconds
B) 40 seconds
C) 46 seconds
D) 48 seconds
E) 240 seconds

Quizplus · Accepted Answer

To find the observed time for the task, simply take the average of the times recorded in the study. 
Average = (46 + 38 + 40 + 34 + 42 + 40)/6 = 40 seconds (rounded to the nearest second) 
Therefore, the observed time for this task is 40 seconds.
