Help the students to visualize this! When you do a confidence interval problem, shade the area that we believe the true parameter is in. Color the tails in a different color to make the students see the region a two-sided hypothesis test is assessing. Therefore - a 90% confidence interval would have 10% leftover in the tails - or 5% on each side.Study with Quizlet and memorize flashcards containing terms like large counts condition, mean sentence, Standard deviation sentence and more. ... ap stats test 6.
