  1. What is the process to test a hypothesis?
    • Identify the problem 
    • Create a hypothesis
    • Test hypothesis against data
  2. What is the Confidence Level?
  3. What is the Significance Level?
  4. What is the representation for Null Hypothesis?
  5. What is the representation for Alternative Hypothesis?
  6. What is the main rule of a hypothesis?
    Hypothesis must be falsibiable
  7. A hypothesis should be mutually what...?
    Mutually exclusive and mutually exhaustive
  8. What is the goal with hypothesis testing?
    Try to reject the null
  9. What is the notation for the one-sided "greater than" alternative/one-tailed, "upper-tail" test?
     
  10. What is the notation for a one-sided, "less than" alternative/one-tailed, "lower-tail" test?
     
  11. What is the notation for a two-tailed test? 
     
  12.  is the chance of what?
    Mistakenly rejecting a true null hypothesis
  13. What is a Type I Error?
    • Rejecting  when it is true
    • Too skeptical
  14. What is a Type II Error?
    • Accepting  what it is false
    • Being too gullible
  15.  = the probability of what?
    P(Making a Type I Error)
  16.  = the probability of what?
    P(Making a Type II Error)
  17.  ?
    1
  18. What are the steps of the Critical Value approach?
    • Set up NULL and Alternative hypotheses
    • Choose a Significance Level 
    • Collect sample data and compute value of test statistic
    • Determine critical value and rejection rule
    • Reject or fail to reject the null
  19. What does the  separate?
    Reject and do not reject regions
  20. What is a p-value?
    The probability of getting  or value more extreme
  21. What are the steps of the p-value approach?
    • Set up NULL and Alternative hypotheses
    • Choose a Significance Level 
    • Collect sample data and compute value of test statistic
    • Use test statistic to compute p-value
    • Reject or fail to reject null
  22. What is the rejection rule for a p-value?
    Reject  if p-value
