Chapter 3, Section 4, Exercise 105 To create a confidence interval from a bootstrap distribution using percentiles, we keep the middle values and chop off some number of the lowest values and the highest values. If our bootstrap distribution contains values for 1000 bootstrap samples, indicate how many we chop off at each end for each confidence level given. Enter the exact answers to all parts.           (a) 85% We should chop off values from each end.   exact number, no tolerance           (b) 80% We should chop off values from each end.   exact number, no tolerance           (c) 90% We should chop off values from each end
