Across
  1. 2. if it states that the parameter is different from the null hypotheses value (not equal to null hypothesis)
  2. 6. if it states that a parameter if larger or smaller than the null hypothesis value (greater/less than or equal to null hypothesis)
  3. 7. a procedure for comparing observed data with a claim (hypothesis) whose truth we want to assess
  4. 8. if the p-value is smaller than a specified value α
  5. 9. H0- a statement of "no difference"; we perform the test to assess the strength of the evidence against it
  6. 11. if the p-value is greater than or equal to α
  7. 12. what you have to check in order to perform a confidence interval
  8. 14. estimate +/- margin of error
  9. 16. if we reject H0 when it is in fact try
  10. 17. how close the estimate tends to be to the unknown parameter
  11. 19. if we fail to reject H0 when it is actually false
Down
  1. 1. when the standard deviation of a statistic is estimated
  2. 3. Ha- the claim we hope or suspect to be true instead of the null hypothesis
  3. 4. our "best guess" at the value of an unknown parameter
  4. 5. a statistic that provides and estimate of the pop. parameter
  5. 10. a level C confidence interval for the mean μ
  6. 12. the success rate of the method that produces the interval
  7. 13. the probability that measures the strength of the evidence against a null hypothesis
  8. 15. n-1
  9. 18. when the population is non-Normal, especially for larger sample sizes
