About Quizlet; How Quizlet works ...When calculating critical values from Table A, students will mistakenly look for the wrong area. For example, when finding the critical value for an 80% confidence interval, naturally students want to look for an area of 0.80. But we know that Table A gives the area to the left of a specific z-score, which includes the 10% area in the left tail. 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. 🧢

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.Jannie Gerber. 6 years ago.
