Rewrite: 3. The confidence interval for the mean will be wider than the confidence level for the median due to the sample mean being typically larger than the median. 4. The larger the sample size, the narrower the confidence level becomes. 5. The main difference between confidence intervals obtained from sampling a Normal Distribution versus a Skewed Distribution is the shape, with Normal Distributions tending to produce symmetric intervals and Skewed Distributions producing asymmetric intervals. However, when increasing the sample size for both distributions, the precision of the estimate improves, leading to narrower confidence intervals. 3. When the confidence level increases, the width of the confidence level increases, this is due to a higher confidence level requiring a larger area under the normal distribution curve which is a result in a wider confidence interval. 4. The Typical width of the confidence interval decreases as the sample size increases due to the standard error of the mean, which is the standard deviation of the sampling distribution of the mean, decreases as the sample size increases
