One inferential thinking question.2. Independence: The sample values must be independent of each other. 3. The 10% Condition: When the sample is drawn without replacement, the sample size should be no larger than 10% of the population. 4. Large Sample Condition: The sample size needs to be sufficiently large.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 ...One is the random condition.

2. Independence: The sample values must be independent of each other. 3. The 10% Condition: When the sample is drawn without replacement, the sample size should be no larger than 10% of the population. 4. Large Sample Condition: The sample size needs to be sufficiently large.When calculating critical values from Table A, students will mistakenly look for the wrong area. For example, when finding the critical value for an 80% confidence interval, naturally students want to look for an area of 0.80. But we know that Table A gives the area to the left of a specific z-score, which includes the 10% area in the left tail.
