Problem regarding the confidence interval

Reference no: EM131106856

Provide one statement AND one question about the following:

A confidence level is a percentage of a sample that indicates a certain section or range of data points that can contain a population parameter. The range itself is the confidence interval.

The larger the sample size, the smaller the width of the confidence level and the smaller the range or confidence interval. As the width of the confidence interval gets smaller, the standard error also decreases. As the confidence interval includes less points or gets smaller, the chance of error decreases because there are less data points involved.

The smaller the sample size, the larger the width of the confidence level and the larger the range or confidence interval. As the width of the confidence interval gets larger, the standard error also increases. As the confidence interval includes more data points or gets larger, the chance of error increases because there are more data points involved.
