If there are 65 successes of 150 trials in the one group, and 115 successes of 200 in another, are the proportion of successes significantly different? Use ?=0.05. They are not significantly different, because the interval boundaries have the same signs. None of these. They are significantly different, because the interval boundaries have the same signs. They are significantly different, because zero is contained in the confidence interval. They are significantly different, because the interval boundaries have different signs. They are not significantly different, because the interval boundaries have different signs.
