5.1 A time study of a finishing operation yielded the following observed times for one element (element A) of a job with a performance rating of 1.20. The allowance is 15% of the job time. Element A Observed Times: Observation(i) 1 2 3 4 5 6 7 8 9 10 Total Time (x),minutes 5 9 10 21 11 5 9 10 21 11 112 5.1.1 Calculate the observed time for element A. (2) 5.1.2 Calculate the normal time for element A. (2) 5.1.3 Calculate the allowance time for element A. (2) 5.1.4 Calculate the standard time for element A. (2) 5.2 In developing standards for one operation, a time-study analyst observed an operator for 40 minutes during which the operator completed 52 parts. The analyst rated the worker at 120%. The base wage for the operator is R26 per hour and the firm's policy is to assign a 15% total operator allowance for fatigue and contingencies. Given the above information, calculate the following: 5.2.1 The Normal Time for the task. (3) 5.2.2 The Standard Time for the task. (3)
