It can be used when the samples are independent, n1ˆp1 ≥ 10, n1ˆq1 ≥ 10, n2ˆp2 ≥ 10, and n2ˆq2 ≥ 10. The formula for the z-test statistic is: z = (ˆp1 − ˆp2) − (p1 − p2) √(ˆp ⋅ ˆq( 1 n1 + 1 n2))

Now look, we can take the number of successes/ failures to find the proportion of successes/failures in the sample: 20/50= 0.4. 0.4=p. 30/50=0.6. 0.6= 1-p. So essentially, we need to first check that the sample size is larger than 30. And if that is met, then we check if the number of successes/ failures in a sample are more than 10.Large Counts Condition: The large counts condition, also known as the "success-failure" condition, is used when applying certain statistical methods to categorical data. It states that for these methods to be valid, both the number of successes and failures must be at least 10.conditions for constructing a confidence interval about a difference in proportions. random. 10%. large counts. confidence interval: random. the data comes from two independent samples or from two groups in a randomized experiment. confidence interval: 10%. when sampling without replacement, check that: n1 < or = to (1/10)N.

So our large counts condition would change to 0.55(85) ≥ 10 & 0.45(85) ≥ 10, which still holds for this particular problem. In other words, when we are given an actual p to check this condition, use it. When we aren't given a p-value, use the next best thing by using your p-hat. 🧢 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?Are you ready for the AP Stats Chapter 8 Test?
