Chi-squared tests require two familiar conditions for inference: Independence. Large Counts. 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). 🗼50 (0.6)=30. 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 ...The 10% Condition in Statistics: Definition & Example.
