The 95% confidence interval for this sample is (10.7, 14.3). Based on the confidence interval for this sample, is it reasonable to claim that Americans read an average of 12 books per year? Yes, because the interval contains 12. No, because the populations are different. No, because the data is based on a sample, not all Americans. Yes, because the average number of books read per year in the sample is 12.5
