Repairing air conditioning units involves five work elements. The Operations Manager, Andre Gordon has timed the workers conducting the tasks seven times, and recorded the results below.

Observations in Minutes

	Job Element	1	2	3	4	5	6	7	Performance Rating(%)
1	Test for coolant	4	5	4	6	4	15*	4	110
2	Test condenser	6	8	7	6	7	6	7	90
3	Replace condenser	15	14	14	12	15	16	13	105
4	Check for cooling	3	4	24*	5	4	3	18*	100

*Indicate time employees spent in lengthy conversation with boss (not job related)

Andre has agreed with the workers to allow a 10% fatigue factor and 10% personal time factor. All observations that are unusual or nonrecurring as shown by asterix (*) are excluded when computing standard time.

Determine the following:

1. Average time for each of the 5 elements of the job 5 marks

2. Normal time for each element 5 marks

3. Total normal time to repair a car air conditioning unit 5 marks

4. The standard time to repair a car air conditioning unit 5 marks
