If a student provided 90% confidence intervals in all ten questions, how many points would we expect him/her to score? Compare the expected and actual scores. 2. If every student provided 90% confidence intervals in all 10 questions, how many students would we expect to get the correct answer for each question? Compare expected and The actual number of students who got the correct answer for each question. 3. Increasing the confidence level, say from 90% to 95% while holding the sample size the same, what will it do to the sample responses (length of confidence interval)? Explain. 4. In the Laboratory Activity, we used 90% confidence interval instead of 100%, why is this so? Why not use a 100% confidence interval at all? What do we need to account for?
