Help students recognize two ideas: The greater the sample size, the closer the Normal approximation is to the binomial distribution. The closer that p is to 0.5, the more symmetric the binomial distribution, and therefore closer to Normal. These two ideas are combined to form the Large counts condition np > 10 and n (1 – p) > 10.

Success/Failure Condition: There should be at least 10 expected successes and 10 expected failures in a sample in order to use the normal distribution as an approximation. Written using notation, we must verify both of the following: Expected number of successes is at least 10: np ≥ 10. Expected number of failures is at least 10: n (1-p) ≥ 10.stats hw on condition interval ap stats: what I do know is that when the large counts condition is met, we can use a Normal distribution to calculate the critical value 𝑧∗ for any confidence level. but what I dont understand are if it has to do with independent probabilities?AP Stats Chapter 7 + 8.
