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		95	%		0.46		0.51		0.41		0.41		0.41		0.41
2		90			1.46		1.46		1.41		1.41		1.41		1.46
3		125			0.81		0.81		0.71		0.76		0.81		0.76
4		110			1.06		1.11		1.06		1.11		1.11		1.16
