A production manager at a Contour Manufacturing plant has inspected the number of defective plastic molds in five random samples of 25 observations each. Following are the number of defective molds found in each sample:

Sample		Number of Defects		Number of Observations in Sample
1		1		25
2		0		25
3		0		25
4		1		25
5		2		25
Total		4		125

Construct a 3-sigma control chart (z = 3) with this information. (If the lower control limit is negative, round the LCL to zero and all other answers to 2 decimal places, e.g. 15.25.)

CL		enter control limit rounded to 2 decimal places
UCL		enter upper control limit rounded to 2 decimal places
LCL		enter lower control limit rounded to 2 decimal places
