In general, the Large Enough Sample Condition applies if any of these conditions are true: You have a symmetric distribution or unimodal distribution without outliers: a sample size of 15 is “large enough.”. You have a moderately skewed distribution, that’s unimodal without outliers; If your sample size is between 16 and 40, it’s ... We have our normal condition, our independent condition and our random condition. Let's do another example. A biologist is studying a certain disease affecting oak tress in a forest. They are curious if there's a difference in the proportion of trees that are infected in the North and South sections of the forest.

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. 🧢AP Statistics Chapter 26: Comparing Counts. Get a hint. chi-square test for goodness of fit.
