A time study was conducted on a job that contains four elements. The observed times 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	%		0.45		0.50		0.40		0.40		0.40		0.40
2		85			1.45		1.45		1.40		1.40		1.40		1.45
3		120			0.80		0.80		0.70		0.75		0.80		0.75
4		105			1.05		1.10		1.05		1.10		1.10		1.15
