Across
  1. 1. the probability that the test will reject the null hypothesis at a chosen significance level alpha when the specified alternative value of the parameter is true
  2. 3. if we reject the null hypothesis when it is true
  3. 4. measures how far a sample statistic diverges from what we would expect if the null hypothesis were true
  4. 8. specified probability
  5. 10. used in tests for means
  6. 14. the claim we seek evidence for
  7. 15. difference between two points on the normal curve
  8. 18. State, Plan, Do, Conclude
  9. 19. statistic that estimates the possible magnitude for error
Down
  1. 1. the probability, assuming Ho is true, that the statistic would take a value as extreme as or more extreme than the one actually observed, in the direction specified by Ha
  2. 2. point on the scale of the test statistic beyond which we reject the null hypothesis
  3. 5. if the pvalue is smaller than the alpha
  4. 6. level of confidence
  5. 7. states that a parameter is larger than the null hypothesis value or if it states that the parameter is smaller than the null value
  6. 9. states that the parameter is different from the null hypothesis value
  7. 11. how much sample is expected to deviate from population
  8. 12. estimate of a population parameter
  9. 13. sample statistic when used to estimate the corresponding population parameter
  10. 16. the claim we seek evidence against
  11. 17. we fail to reject the null hypothesis when the alternative hypothesis is true
