Chi-squared tests require two familiar conditions for inference: When sampling without replacement, we should check the 10% condition for independence (n < 10%N) For our large counts condition, we need to verify that all of our expected counts are at least 5 (similar to other chi-square test set-ups). 🗼. In a question, it says that a true-false exam is used to discriminate between well-prepared students and poorly prepared students.

The company conducts a chi-square goodness-of-fit test to investigate whether there is a change in the distribution of number of cards used from last year to this year. The value of the chi-square test statistic was χ2=7.82 with a corresponding p-value of 0.02. 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?
