d.Circle a confidence interval that does not accurately estimate the population proportion. Why doesn’t this interval contain p? e.What percentage of the confidence intervals plotted here accurately estimate the population proportion? (In other words, what percentage of the confidence intervals plotted here contain p=0.80?) f. In the long run, if we collected thousands and thousands of random samples, what percentage of the associated confidence intervals will contain p? Why do you think so? What do you think “95% confident” means?
