Quizplus · Accepted Answer

The observed time for the task is simply the average time taken in the six observations. Adding the times and dividing by six, we get:

(99+87+90+81+93+90)/6 = 540/6 = 90 seconds.

Therefore, the observed time for cleaning a cat cage is 90 seconds, and the best choice is B.
