Table VII:

Type I error rates for various confidence interval methods using bivariate normal data with a correlation of .3 ^e

Confidence Interval Method	Type I error rate
Standard Confidence interval	4.5%
Univariate Bootstrap NDE k=1	4.4%
Standard Bootstrap NDE k=1	5.5%
Univariate Bootstrap NDE k=2^*	18.5%
Standard Bootstrap NDE k=2^*	19.2%
Univariate Bootstrap DE k=1^*	17.8%
Standard Bootstrap DE k=1^*	19.2%
Univariate Bootstrap DE k=.5	5.1%
Standard Bootstrap DE k=.5	5.7%

(N)DE: (Not) Double Entered; k: Bootstrap resample size is that multiple of input data size (e.g., if not double entered, and k =1, bootstrap resample size is n, if double entered 2n).

Significantly greater Type I error rate than expected p < .05.
