If a 90% confidence interval for the difference of proportions contains some positive and some negative values, what can we conclude about the relationship between p1 and p2 at the 90% confidence level? There is a positive difference between p1 and p2. There is no difference between p1 and p2. There is a negative difference between p1 and p2. We cannot make a conclusion about the relationship between p1 and p2.
