Analyze another fileStandard-library analysis: did the conversion rate really differ between two groups? Map a binary outcome (0/1, yes/no, TRUE/FALSE, converted/not) and a two-level group column and get each group's rate with a Wilson 95% confidence interval, the two-sample proportion z-test with a continuity-corrected chi-square cross-check, the absolute difference with a Newcombe hybrid confidence interval, the relative change as computed, and an automatic Fisher's exact fallback — clearly disclosed — whenever any cell count is too small for the z-test.
