Confident conclusions
Program 10 compares formal statistical inference, as opposed to exploratory data analysis, based on calculations of probability. Defines confidence intervals and demonstrates how to find a 95% confidence interval for a population proportion p. Application examples are drawn from a health study, manufacturing, and Gallup poll interviews.
