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.

You can complete these calculations using either the sample proportion, or number of successes from your sample data.
