1. The width of the 95% CI is larger because we have more confidence in the 95% interval. 2. The width of the 95% CI is larger because there is a greater probability that it contains the true ratio of standard deviations. 3. The 90% CI is better since it has smaller width than the 95% CI. 4. The 95% CI is wider because it is 5% more likely to contain the true ratio of standard deviations. True statement: (c) A 90% lower-confidence bound on Round your answer to 3 decimal places.
