chapter 3
A surgeon would like to estimate the proportion of handsurgeries that involve serious complications post-operation. A sample of 20 surgeries revealed that 7 we accompanied by seriouscomplications.
Estimate a 99% confidence interval for the proportion of handsurgeries with serious complications.
1) Estimate the value of the population proportion. (ExactValue)
2) What is the margin of error? (Round to 3 decimal placesas needed).
3) What is the lower bound of the confidenceinterval? (Round to 3 decimal places as needed).
4) What is the upper bound of the confidenceinterval? (Round to 3 decimal places as needed).
5) What is the margin of error if the confidence level isreduced to 0.90?
