Students estimate the true mean of a population when the standard deviation is known by finding the sample mean, margin of error and confidence interval.
Students work through self-check questions to review the standard normal curve and the percentiles.
The Central Limit Theorem is also reviewed and built on to enable students to construct confidence intervals when trying to estimate the mean of the population.
