Across
  1. 5. fail to reject Ho when Ho is false
  2. 7. statistic that provides an estimate for pop. parameter
  3. 8. an inference procedure is called this if the prob. calculations involved in that procedure remain fairly accurate when a condition for using the procedure is violated
  4. 9. probability that the statistic would take a value as extreme or more than the one actually observed, assuming Ho is true
  5. 11. used to specify a particular t distribution
  6. 14. we reject Ho when Ho is true
  7. 15. data are ( ) if the p-value is smaller than alpha
  8. 18. when the standard deviation of a statistic is estimated from the data
  9. 20. random, normal, independent
Down
  1. 1. tells how close the estimate is to the unk. parameter
  2. 2. claim tested by a statistical test
  3. 3. assesses the evidence provided by data against a null hypothesis in favor of an alternative hypothesis
  4. 4. claim about the population that we are trying to find evidence for
  5. 6. estimate +/- margin of error
  6. 10. value of the point estimator from a sample
  7. 12. alternative hypothesis is ( ) if it states that the parameter is different than the null value
  8. 13. probability that the test will reject Ho at a chosen alpha level when the specified alternative value of the parameter is true
  9. 16. gives the success rate of the method for calculating the confidence interval
  10. 17. similar but different than the z distribution, has more area in the tails
  11. 19. alternative hypothesis is ( ) if it states that a parameter is larger or smaller than the null value
