Daily samples of 50 checks each were taken at a bank from an encoding machine (which records the amount of a check). The data on the number of defective entries found in each sample is provided in the table below (there is no file attachment for this data):

Sample	Number Defective
1	1
2	4
3	2
4	4
5	0

Using the data from the 5 samples, please calculate and report the value for the center line (only - no need for LCL and UCL) for the proportion (p) control chart, rounding your response to three spaces after the decimal.
