The conditions we need for inference on a mean are: Random: A random sample or randomized experiment should be used to obtain the data. Normal: The sampling distribution of x ¯. ‍. (the sample mean) needs to be approximately normal. This is true if our parent population is normal or if our sample is reasonably large ( n ≥ 30) ‍.Conditions for Inference about a Population Mean Random Sample - The data are a random sample from the population of interest. 10% Rule - The sample size is no more than 10% of the population size: 𝑛 Q1 10 𝑁 Large Counts/Normality – If the sample size is large (𝑛 R30), then we can assume normality for any shape of distribution.Large Counts Condition. 10% Condition. n must be greater than or equal to 1/10 of N. ...

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. One question asking students to do a chi-square goodness of fit test, and one question asking students to do chi-square test with a two-way ... AP STATS EXAM REVIEW. A randomized experiment was performed to determine whether two fertilizers, A and B, give different yields of tomatoes. A total of 33 tomato plants were grown; 16 using fertilizer A, and 17 using fertilizer B. The distributions of the data did not show marked skewness and there were no outliers in either data set. The 10% condition states that sample sizes should be no more than 10% of the population. Whenever samples are involved in statistics, check the condition to ensure you have sound results. Some statisticians argue that a 5% condition is better than 10% if you want to use a standard normal model. For example, the 10% condition normally applies ... 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.Study with Quizlet and memorize flashcards containing terms like Distribution, Sampling Distribution, A population has ____ possible sampling distributions and more.Although the sample size is less than 30 ( n = 19), this is satisfied because the boxplot for the sample differences shows an approximately symmetric distribution with no outliers.

Let them choose which approach and give full credit for both approaches (just make sure they check the Large Counts condition if they use the Normal approximation.) One inferential thinking question.Step 3: Correct mechanics, including the value of the test statistic and p-value (or rejection region). t ≈ 3.12. 8 The p-value, based on a t-distribution with 8 − 1 = 7 degrees of freedom, is 0.008.
