WebQ2: A 99% confidence interval is wider than a 95%, all else being equal. Therefore, it's more likely that it will contain the true value. See the distinction above between precise and accurate. If I make a confidence interval narrower with lower variability and higher sample size it becomes more precise because the values cover a smaller range. WebStep 1: Find the number of observations n (sample space), mean X̄, and the standard deviation σ. Step 2: Decide the confidence interval of your choice. It should be either 95% or 99%. Then find the Z value for the corresponding confidence interval given in the table. Step 3: Finally, substitute all the values in the formula. cloaksmith twitter https://lrschassis.com
