Quizplus · Accepted Answer

To calculate the observed time (OT), we need to sum the six recorded times and divide by six. 
(14 + 12 + 10 + 11 + 14 + 11) / 6 = 12.0 seconds
Therefore, the observed time for this task is 12.0 seconds or 40 seconds rounded to the nearest whole number. Choice B is the best answer.
