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.AP AUDIO: Midwest tornadoes flatten homes in Nebraska suburbs and leave trails of damage in Iowa. Omaha resident Pat Woods says they saw the tornado and took cover. In one area of Elkhorn, dozens of newly built, large homes were damaged. At least six were wrecked, including one that was leveled, while others had the top half ripped off.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))Study with Quizlet and memorize flashcards containing terms like Describing a scatterplot, Interpreting p-value, Interpreting Expected Value/Mean and more.The 10% Condition says that our sample size should be less than or equal to 10% of the population size in order to safely make the assumption that a set of Bernoulli trials is independent. Of course, it’s best if our sample size is much less than 10% of the population size so that our inferences about the population are as accurate as possible.

Note: In some textbooks, a “large enough” sample size is defined as at least 40 but the number 30 is more commonly used.

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 10.2.
