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.

Chi-squared tests require two familiar conditions for inference: When sampling without replacement, we should check the 10% condition for independence (n < 10%N) For our large counts condition, we need to verify that all of our expected counts are at least 5 (similar to other chi-square test set-ups). 🗼.Study with Quizlet and memorize flashcards containing terms like continuous random variable, discrete random variable, binomialpdf and more.AR.

There are $\frac{205}{250}$ well-prepared students and $\frac{137}{250}$ poorly prepared students … The Large Counts Condition is satisfied when both np and n (1-p) are greater than or equal to 10, where n is the sample size and p is the probability of success. In other words, if the number of successes and failures in the sample is large enough, then we can assume that the distribution of the count of successes follows a normal distribution. The response does not satisfy component 3 because, although the response correctly names the test, the z-statistic formula provided is not correct. Section 1 was scored partially correct (P). Question 4 (continued) In section 2 the response satisfies components 1 and 2 by correctly checking the conditions.Study with Quizlet and memorize flashcards containing terms like Point Estimator, Point estimate, Confidence interval and more.To check if our sampling distribution is normal, we need to verify that the expected successes and expected failures of our study is at least 10.
