Which of the following factors do not affect the width of the confidence interval?
Answer:
The width of a confidence interval is impacted by several factors, but certain factors do not influence its width. These include the confidence level and the population variance. The confidence level determines the level of certainty with which the parameter of interest falls within the interval, but it does not affect the width itself. Similarly, the population variance, whether known or unknown, does not directly impact the width of the confidence interval. Factors such as sample size, variability of the data, and the standard error of the estimate are key components that affect the width of the confidence interval.
