Question

A 99 percent confidence interval has higher confidence but less precision than a 95 percent confidence interval.

True or False

Answer 1

The above statement is TRUE.

95 percent confidence interval is narrower than 99 percent confidence interval

Hence 95 percent interval is more precise than 99 percent interval.

Explanation: If a confidence interval is made narrower with lower viability and higher sample size, it becomes more precise, the likely values cover a smaller range. If the coverage of this interval is increased by using a 99 percent calculation, the interval becomes more accurate (less precise...understand the difference), the true value is more likely to be within the range.
