A time study was conducted on a task that consists of four elements. The observations and performance ratings for six cycles are shown in the following table.

		Observations (minutes per cycle)
Element	Performance Rating	1	2	3	4	5	6
1...........	90%	0.44	0.50	0.43	0.45	0.48	0.46
2...........	85	1.50	1.54	1.47	1.51	1.49	1.52
3...........	110	0.84	0.89	0.77	0.83	0.85	0.80
4...........	100	1.10	1.14	1.08	1.20	1.16	1.26

1. Calculate the average time for each element.
2. Calculate the normal time for each element.
3. Assuming an allowance factor of 15 percent of workday, calculate the standard time for this task.
