Question types

  • 7 computation questions (1 pt. each)

    • 3 Find the critical value(s) for either z or t (the student will determine which is appropriate) questions
    • 2 compute the appropriate test statistic (either z or t)
    • 2 compute the p-value questions
  • 2 multiple choice conceptual questions (1 pt. each)

  • 4 TRUE/FALSE conceptual questions (0.5 pt. each)

  • An end-to-end statistical test question (with 9 questions embedded within it; 1 pt. each)

    • Determine the null hypothesis (multiple choice)
    • Determine the alternative hypothesis (multiple choice)
    • Select an appropriate level of significance (multiple choice)
    • Determine the appropriate test and the reason for that test (multiple choice)
    • Determine whether the test is one-tailed or two tailed and the reason for this (multiple choice).
    • Compute the critical value based on an appropriate level of significance (numerical answer)
    • Compute the appropriate test statistic (numerical answer)
    • Determine the decision (multiple choice)
    • Determine which assumptions may be violated (multiple choice)
