Doubling the population standard deviation σ has the effect of doubling the width of the confidence interval estimate of μ.

Population Standard Deviation

A measure of the dispersion or spread of a set of data points in a population dataset.

Confidence Interval

A range of values, derived from sample data, that is likely to contain the value of an unknown population parameter with a certain level of confidence.

Population Mean

The average of all observations or scores in a population.

  • Understand the impact of variations in sample size and population standard deviation on the confidence interval.
