Summary Statistics
Perform Inference
Inference procedure:
Simulate mean difference
Simulate sample mean
1sample t interval for μ
1sample t test for μ
1sample χ² interval for σ
1sample χ² test for σ
Sign test for paired data
Sign test for population median
Wilcoxon signed rank test for paired data
Wilcoxon signed rank test for population median
Confidence level:
%
Alternative hypothesis:
μ >
μ <
μ ≠
