Use the preparation materials (I also suggest reviewing the preparation questions for the [1-Sample t-Test](1Samplet) and [2-Sample t-Test](2Samplet) modules) to prepare hand-written answers for the following questions. Please ask any questions on the "Questions -- Preparation Guide" on the course Team (see link on the homepage.)
  1. What R function is used to perform a 1-Sample t-Test with raw data? What is the form of the first argument to this function?
  2. What format must the data be in to perform a 2-Sample t-Test in R?
  3. What R function is used to perform a 2-Sample t-Test with raw data? What is the form of the first argument to this function?
  4. What R function is used to perform the test for equal variances? What is the form of the first argument to this function?
  5. What is the purpose of the mu= argument to t.test()?
  6. What is the purpose of the alt= argument to t.test()? What “values” can it take and what do those “values” mean?
  7. What is the purpose of the conf.level= argument to t.test()?
  8. What questions do you have from this reading that you would like me to address? [Please be as specific as possible. Don’t just say “everything” or “I don’t understand anything.” Of course, you can ask questions about the reading before class on MS Teams (see link above).]
