Chapter 12: More about Tests and Intervals Summarize issues in statistical inference by posing three questions when looking at data. Am I surprised (Should I reject the null hypothesis) How surprised am I (What’s the P-value) What would not surprise me (Write a confidence interval for the parameter) Interpretation of the P-value See the end of Chapter 10 notes. In addition for most of the Chapter 10 and Chapter 11 hypothesis test examples I gave an interpretation of the p-value. Critical Values in Hypothesis Testing We test hypotheses about parameters. So far the parameters we have used in hypotheses are the mean of the population (μ) and the population proportion (p). The burden of proof falls on us to find evidence against the null hypot
