For a one-sample confidence interval for a proportion, this would be the correct calculation. But there is a slight change for the test of significance.To relate the Central Limit Theorem to confidence intervals, we need to look at the formula for a confidence interval.

So our large counts condition would change to 0.55(85) ≥ 10 & 0.45(85) ≥ 10, which still holds for this particular problem.

The 10% condition states that sample sizes should be no more than 10% of the population. Whenever samples are involved in statistics, check the condition to ensure you have sound results.

For example, the 10% condition normally applies ...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.
