Lab 7: Normal Distribution and t-distribution

Learning Objectives

• Become comfortable using Normal and t-distributions for statistical inference.
  
• Learn how to construct confidence intervals and perform tests using the t.test() and prop.test() functions in R.
• Compare simulation and formula-based methods of inference.
• Understand that a test for a difference in (means, proportions) may be significant even when confidence intervals for the individual groups overlap.
• Compute confidence intervals and tests for paired data using t.test()
