Conditions. Just like we had with other inference procedures, our test hinges on certain conditions being met. With chi square testing, we need the following two conditions: . Our sample was taken randomly or treatments were assigned randomly in an experiment. Large Counts: All expected counts are at least 5.

Check the Random and Large Counts conditions for performing a significance test about a population proportion. Calculate the standardized test statistic for a significance test about a population proportion. Find the P-value for a one-sided significance test about a population proportion using Table A or technology.This idea becomes the critical value for a confidence interval. In Chapter 4, students learned that the purpose of a random sample is so that we can generalize to the larger population. In this chapter, this idea becomes the Random condition for inference. In Chapter 6, students learned to check the 10% condition in the binomial setting to be ...The observed counts are to be stored in L1. The expected counts are to be stored in L2.

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.

Help students recognize two ideas: The greater the sample size, the closer the Normal approximation is to the binomial distribution. The closer that p is to 0.5, the more symmetric the binomial distribution, and therefore closer to Normal. These two ideas are combined to form the Large counts condition np > 10 and n (1 - p) > 10.
