AP STATISTICS: Chapter 11 (Sections 11.1, and 11.2) Chi-Square Statistic. Click the card to flip 👆. The chi-square statistic is a meaure of how far the observed counts are from the expected counts. The formula is x^2= sum of (observed-expected)^2/expected. You do (observed-expected)^2/expected for each category and then add them.Help the students to visualize this! When you do a confidence interval problem, shade the area that we believe the true parameter is in. Color the tails in a different color to make the students see the region a two-sided hypothesis test is assessing. Therefore - a 90% confidence interval would have 10% leftover in the tails - or 5% on each side.One is the random condition. I'll write 'em up here. The random condition. And that would be that there's truly a random sample of games. And it tell us right here, he took a random sample of his 24 games. So we meet that condition.

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))The Large Sample Condition: The sample size is at least 30.
