Reconsider the previous exercises about the average number of states all students at the author’s school have visited. Recall that in the author’s sample of 50 students the average number of states the students had visited was 9.48 and the standard deviation was 7.13.
a. Use the Theory-Based Inference applet to find and report an 88% confidence interval and interpret this interval in the context of the study.
b. Explain why you cannot use a simulation-based 2SD method to find an 88% confidence interval for the average number of states all students at the author’s school have visited.
