Calculate the​ 95% confidence intervals for the proportion of children​ surviving, and the proportion of​ non-crew adult passengers surviving. We want to use the given data to make inferences about the general population of all large boat​ crashes, so the data set should be treated as a random sample for this purpose.


  1. The​ 95% confidence interval for survival rate amongst​ non-crew adults runs from?
     (Round to one decimal place as needed. Use ascending​ order.)
