The data below represent time study observations for an assembly operation.Assume a 7% allowance factor.What is the normal time for element 3?

Question

Quizplus · Accepted Answer

To find normal time, we need to use the formula:
Normal time = (sum of observations/time observations) x allowance factor
For element 3, the observations are: 2.0, 2.2, 1.8, 2.1, 1.9
Sum of observations = 10.0
Time observations = 5
Allowance factor = 7% or 0.07
Normal time = (10/5) x 0.07 = 0.14
Therefore, normal time for element 3 is 1.96 minutes (rounded to two decimal places). Hence, the answer is B.
