Summary

In this chapter, we examined the law of large numbers and how the stability of the sample mean statistic is affected by sample size. Through the CLT, the theoretical underpinnings of confidence intervals and hypothesis testing were examined. Confidence intervals were used to describe sample statistics, such as sample mean, sample proportion, and margin of error. Hypothesis testing was conducted to evaluate two opposing hypotheses using the evidence of a collected sample.

The next chapter begins your study of calculus, where you will examine such topics as the instantaneous rate of change and finding the slope of a curved line. After studying that, we will look at integration, which is finding the area underneath a curve. Finally, we will use derivatives to find optimal values of complicated equations and graphs.
