- Students will interpret a confidence level as the degree of confidence in the process used to produce an interval that will contain the true mean of the population.

- confidence interval
- confidence level
- population parameter

This lesson involves generating a confidence interval for the mean of a population from a random sample of size *n* and considering how certain one can be that this interval would contain the actual population mean.

As a result, students will:

- Experiment with different confidence levels and finally investigate the relationship between confidence levels and sample size.
- Use the actual population mean to check their estimates and to develop an understanding of the meaning of confidence level.
