• A) \(( 0.616,0.686 )\); we are \(98 \%\) confident that the proportion of college seniors who are planning to pursue a graduate degree is between \(0.616\) and \(0.686\).
• B) \(( 0.620,0.682 )\); we are \(98 \%\) confident that the proportion of college seniors who are planning to pursue a graduate degree is between \(0.620\) and \(0.682\).
• C) \(( 0.621,0.680 )\); we are \(98 \%\) confident that the proportion of college seniors who are planning to pursue a graduate degree is between \(0.621\) and \(0.680\).
• D) \(( 0.612,0.690 )\); we are \(98 \%\) confident that the proportion of college seniors who are planning to pursue a graduate degree is between \(0.612\) and \(0.690\). Construct a 95% Z-interval or a 95% t-interval about the population mean. Assume the data come from a population thatis approximately normal with no outliers.
