    A. Suppose you take a sample of size n from a population and calculate a statistic from that sample. The statistic could be a sample proportion p, a sample mean x, or another statistic. Then suppose we repeat this process over and over again until we find all possible samples of size n from the population (this is a theoretical idea) and we calculate the same statistic from 1. each sample. The collection of all of the statistics calculated is...

    A 95% confidence interval for a population proportion p is found to be (0.52, 0.58). What does this mean? A. There is a 95% probability that the actual value of p is between 52% and 58%. B. If many simple random samples of the same size were taken from the population, and a confidence interval were constructed for each one, then about 95% of them would contain the actual value of p. C. 95% of all sample proportions are between...
