Inference procedure:
Simulate difference in percents/proportions
2sample z interval (p₁  p₂)
2sample z test (p₁  p₂)
Chisquare test for homogeneity
Confidence level:
%
Alternative hypothesis:
p₁  p₂ > 0
p₁  p₂ < 0
p₁  p₂ ≠ 0
Category to indicate as success:
Simulates the distribution of the difference in sample
of successes when the observed successes and failures are combined, shuffled, and redistributed into two groups that match the sizes of the original groups.
