Jan 3, 2023 · Large Counts Condition: The large counts condition, also known as the "success-failure" condition, is used when applying certain statistical methods to categorical data. It states that for these methods to be valid, both the number of successes and failures must be at least 10. The z-test is a statistical test for comparing the proportions from two populations. It can be used when the samples are independent, n1ˆp1 ≥ 10, n1ˆq1 ≥ 10, n2ˆp2 ≥ 10, and n2ˆq2 ≥ 10. The formula for the z-test statistic is: z = (ˆp1 − ˆp2) − (p1 − p2) √(ˆp ⋅ ˆq( 1 n1 + 1 n2))A multiple choice question which gives a two-way table and asks for a test statistic and P-value only (students should use their calculator for this.) On the free response, you should have two questions.
