Question Set 2_B: Step 1. Interpret the confidence interval you computed above by completing the following sentence I am 95% confident that... Question Set 2: California Bar Exam The State Bar of California is considering changing its exam structure such that instead of 200 multiple-choice questions, there will be 180. Before making any changes permanent, they first want to collect data to compare the outcomes of the two structures. They have obtained a representative sample of 85 Law students and randomly assigned each to take either the new or old exam. The summarized sample data is given in the table below. Sample Data Summary Exam N Mean SD New 42 65.9 5.9 Old 43 63.6 3.2 Question Set 2_A: Use Minitab to construct a 95% confidence interval to estimate the mean difference in the bar exam scores of the two groups. Include the supporting Minitab output. Question Set 2_C: For a hypothesis test for two independent means, what two assumptions must be met to use a t distribution? Are both assumptions met for the data above? Hand calculations are not required. Question Set 2_F: State a real-world conclusion. Question Set 2_D: Compute the test statistic. Question Set 2_B: Step 2. Briefly explain the implication of the confidence interval containing "O" (or not containing "O", whichever is appropriate for this result). Question Set 2_E: Decide to reject or fail to reject the null hypothesis.
