In the example listed above, let's say that we were given the proportion that 70% of all teenagers pass their math class.therefore, the response satisfies component 2 of section 1. Although the expected count condition is stated and the expected counts are listed and labeled, the response indicates the condition results in "normality," which is incorrect.

To relate the Central Limit Theorem to confidence intervals, we need to look at the formula for a confidence interval. For a normal distribution with a population mean μ and sample mean x̄, the confidence interval would be x̄ ± z* (σ/√n). So if n is small, ie less than 30, the confidence interval would be larger (less confidence in our ...AP Stats Chapter 10 Cheat Sheet from GSarkar. AP Stats Chapter 10 Cheat Sheet from GSarkar. ...
