If we change an estimate with a 95% confidence interval to one with a 99% confidence interval, (A) we can expect the width of the confidence interval to widen.
What is a confidence interval?
We have a 5% probability of being incorrect with a 95% confidence interval.
We have a 10% probability of being incorrect with a 90% confidence interval.
A 95% confidence interval is narrower than a 99% confidence interval (for example, plus or minus 4.5 percent instead of 3.5 percent).
We can anticipate an increase in the width of the confidence interval if we convert an estimate with a 95% confidence interval to one with a 99% confidence interval.
The 68-95-99.7 Rule states that 95% of values fall within two standard deviations of the mean, hence to calculate the 95% confidence interval, you add and subtract two standard deviations from the mean.
Therefore, if we change an estimate with a 95% confidence interval to one with a 99% confidence interval, (A) we can expect the width of the confidence interval to widen.
