      inflation is higher with reference to Quarterly Projection of CPI Inflation?
      A 50% Confidence Interval Correct Answer Incorrect Answer
      B 60% Confidence Interval Correct Answer Incorrect Answer
      C 70% Confidence Interval Correct Answer Incorrect Answer
      D 80% Confidence Interval Correct Answer Incorrect Answer
      E 90% Confidence Interval Correct Answer Incorrect Answer

      Solution

      More the Confidence Interval more is the range. Refer ESI Class No.1 in 120 Days Plan. Take this example: In no negative marking exam consisting 50 MCQs, the range of marks is 0-50, so I can tell with 100% confidence that candidate will get 0-50 marks. But when I expect marks 40-45 then probability of success will reduce. So, for exam purpose just remember higher confidence interval means more probability getting answer correct and it has wider range.
