Large counts condition ap stats

The conditions are Random and Large Counts. The large counts condition is different than the one we use for proportions: the expected counts must be greater than 5. We already calculated the test statistic yesterday but we didn't find the P-value using table C. To use table C we need the degrees of freedom, df = n - 1, where n is the number ...

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.6.1 - Intro to Sampling Distributions. Statistical Concepts Covered.
