AP Statistics Unit 10 Comparing Two Populations or Groups. We use when estimating a difference in two proportions. No hypotheses are required. Uses random and large counts conditions. "P1 - P2 is the true difference in proportion of___". The conditions are random and large counts. The conditions we need for inference on one proportion are: Random: The data needs to come from a random sample or randomized experiment. Normal: The sampling distribution of p ^. ‍. needs to be approximately normal — needs at least 10. ‍. expected successes and 10. ‍. expected failures. This is known as random variation. The p-value that is calculated in a statistical test reflects the likelihood that the observed difference between the variables occurred by chance. If the p-value is very low (e.g., below 0.05), then it is unlikely that the observed difference occurred by chance, and we can conclude that there is a significant ...One is the random condition.
