The confidence interval becomes smaller.

no,these are not the same thing.The values at each end of the interval are called the confidence limits.

The width of the confidence interval increases.

Narrow because there is less of a chance for people to mess up

Assuming that other measures remain the same, as the sample estimate increases both ends of the confidence interval will increase. In effect, the confidence interval will be translated to a higher value without any change in its size.Assuming that other measures remain the same, as the sample estimate increases both ends of the confidence interval will increase.

The confidence interval becomes wider.

how are alpha and confidence interval related

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.

The confidence interval is not directly related to the mean.

The confidence interval becomes smaller.

No, it is not. A 99% confidence interval would be wider. Best regards, NS

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.

The width of the confidence interval increases.

A confidence interval of x% is an interval such that there is an x% probability that the true population mean lies within the interval.
