If you were to construct a 99% confidence interval like the 95% confidence interval you constructed in
Question:
If you were to construct a 99% confidence interval like the 95% confidence interval you constructed in #18 by testing different values for π and seeing whether or not they are plausible, how would the width of the 99% confidence interval compare to that of the 95% confidence interval? Find this 99% confidence interval to back up your claim.
