Widget: Verify the Conditions to Make Inferences About Proportions (2-sample)
This widget calculates n1·p̂ , n1·(1 - p̂), n2·p̂ , n2·(1 - p̂) to the nearest whole number, where p̂ = x1+x2⁄n1+n2. These calculations allow you to verify the conditions to conduct a hypothesis test about, or construct a confidence interval for 2 proportions.
