A medical facility does MRIs for sports injuries. Occasionally a test yields inconclusive results and must be repeated. Using the following sample data and n = 197.

SAMPLE
	1	2	3	4	5	6	7	8	9	10	11	12	13
Number of retests	1	1	2	0	1	2	2	0	2	7	3	2	1

Determine the upper and lower control limits for the fraction of retests using two-sigma limits. (Do not round intermediate calculations. Round your final answers to 4 decimal places. Leave no cells blank - be certain to enter "0" wherever required.)
