1. Suppose you want to construct a confidence interval for a population proportion. Which of the following, if it were true, would prevent you from being able to assume that the distribution of the sample proportion is nearly normal? None of these options. n= 104. Out of these 104 there are only a few successes (15), but relatively many failures (89). O n= 104. These observations are a simple random sample and make up less than 10% of the population. n= 104. Out of these 104 there are an equal number of successes and failures (52 each). 2. When checking conditions for calculating a confidence interval for a proportion, you should use which number of successes and failures? Expected (based on the null value) Depends on the context Not applicable. The number of successes and failures (observed or otherwise) is not part of the conditions required for calculating a confidence interval for a proportion. Observed
