1. My bootstrap distribution after 1000 resamples is shown in the histogram and summary statistics below.
Based on this information, which would be better, a t distribution interval or a bootstrap percentile interval?
A. the bootstrap t interval
B. the bootstrap percentile interval
C. Either would be acceptable.
2. An advantage of the permutation test over the t test for a difference in means is that
A. it gives accurate P-values even when the distributions are not normal.
B. it tests a more general hypothesis.
C. Both choices are true.
3. Permutation tests cannot be used for
A. tests when we believe the two populations differ under the null hypothesis.
B. matched pairs designs where we believe only random differences occur.
