[A, SfS] Chapter 5: Confidence Intervals: 5.5: CI for proportion
Confidence Interval for a Population Proportion
A study in 2005 reports that out of #10501# total knee arthroplasties, #859# resulted in complications within six months of the surgery.
If we regard this as a random sample from all possible knee arthroplasties, compute the margin of error of a #95\%# confidence interval for the proportion of all possible knee arthroplasties that result in complications within six months of surgery. Use #3# decimal places.
Margin of error #=#
