Use some ideas from this blog post to see other ways to present the 10% and large counts condition. Always ask the students what selecting "a" object means. Once the students realize that n = 1, they can use the sample procedures they have been doing when we give them a sample size.The large counts condition can be expressed as np ≥ 10 and n (1-p) ≥ 10, where n is the sample size and p is the sample proportion. This means that both the number of successes (np) and the number of failures (n (1-p)) in the sample should be at least 10.Unit 3 AP Stats Vocab. 20 terms. IOSS23. Preview.

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.The Large Counts condition is not met because there are only 7 failures in the control area.

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 10.Study with Quizlet and memorize flashcards containing terms like Parameter, Statistic, Distribution and more.Study with Quizlet and memorize flashcards containing terms like Describing a scatterplot, Interpreting p-value, Interpreting Expected Value/Mean and more.Chi-Square Test of Homogeneity.
