With a 2 proportion z test, we have to combine our proportions to create a combined p-hat. This is what we use to find our expected failures and successes. 🎩

lesson to continue to emphasize why we need these conditions. Use some ideas from this blog post to see other ways to present the 10% and large counts condition. Always ask the students what selecting "a" object means. Once the students realize that n = 1, they can use the sample procedures they have been doing when we give them a sample size.
