In this chapter, you will learn how to:

8.1 Differentiate between population parameters and sample statistics.

8.2 Define the concept of the central limit theorem and discuss its significance.

8.3 Calculate standard errors for sample means and sample proportions.

8.4 Construct and interpret confidence intervals for population parameters, demonstrating the ability to convey the uncertainty and precision of estimates.

8.5 Evaluate the relationship between sample size and the margin of error in polls.

8.6 Apply Student’s t-distribution to make inferences about population means from small samples.
