decrease
To decrease the width of a confidence interval without sacrificing the level of confidence, you can increase the sample size. A larger sample provides more information about the population, which reduces the standard error and narrows the interval. Additionally, using a more precise measurement technique can also help achieve a narrower interval. However, it's important to note that increasing the sample size is the most effective method for maintaining the desired confidence level while reducing width.
As the confidence coefficient increases, the width of the confidence interval also increases. This is because a higher confidence level requires a larger margin of error to ensure that the true population parameter is captured within the interval. Consequently, while the sample size remains fixed, the interval becomes wider to accommodate the increased uncertainty associated with a higher confidence level.
Confidence level 99%, and alpha = 1%.
The confidence level for a confidence interval cannot be determined solely from the interval itself (46.8 to 47.2) without additional context, such as the sample size or the standard deviation of the data. Typically, confidence levels (e.g., 90%, 95%, or 99%) are established based on the statistical method used to calculate the interval. To find the exact confidence level, more information about the underlying statistical analysis is needed.

confidence level
Confidence intervals represent an interval that is likely, at some confidence level, to contain the true population parameter of interest. Confidence interval is always qualified by a particular confidence level, expressed as a percentage. The end points of the confidence interval can also be referred to as confidence limits.

No. The width of the confidence interval depends on the confidence level. The width of the confidence interval increases as the degree of confidence demanded from the statistical test increases.
