Statistical Inference for Paired Data

• Confidence intervals and hypothesis tests for paired data are based on differences.
• Example dealing with chocolate milk and time until exhaustion (Exercise 11.24 on p. 544)

Nonparametric Procedures for Inferences about a Population Median

• Sign Test (Stat > Nonparametrics > 1-Sample Sign)
  

Class Exercises

• 11.25 (with t procedures and with sign procedures)
• 11.27, 11.31, 11.32, and 11.34

Statistical Inference for Two Proportions

• Point Estimation
• Confidence Intervals
  • Traditional C.I.'s (Exact and Approximate)
• Hypothesis Testing

Example - Exercise 11.47 on page 559

Class Exercises

• 11.43, 11.48, 11.53

We will have a problem session on Wednesday to discuss the class exercises. Our second exam will be on Friday!
