13 Analyzing a single numerical variable

Tutorial learning objectives

  • Learn about the one-sample t-test, which compares the mean from a sample of individuals to a value for the population mean (\(\mu_0\)) proposed in the null hypothesis
  • Learn the assumptions of a one-sample t-test
  • Learn how to calculate an exact confidence interval for a population mean (\(\mu\))
  • Learn the confidence interval approach for testing the plausibility of a hypothesized value for \(\mu\)
