Across
  1. 2. claim tested by a statistical test
  2. 4. probability remains accurate even when a condition is violated
  3. 5. z or t scores used to find the confidence interval
  4. 8. value obtained from a sample
  5. 12. when p value is smaller than alpha
  6. 17. probability of correctly rejecting the null when the null is false
  7. 18. statistic that provides an estimate of a population parameter
  8. 19. fail to reject the null when the null is null is false
Down
  1. 1. a range the population perimeter is likely to fall in
  2. 3. how far the statistic differs what we would expect if the null was true
  3. 6. like a normal curve,but with more area in the tails
  4. 7. claim we are trying to find evidence for
  5. 9. value of the statistic from the sample
  6. 10. alternative is greater than or less than the null
  7. 11. how close the estimate tends to be to the unknown parameter
  8. 13. use when standard deviation of the statistic is estimated from the sample
  9. 14. in x% of all possible samples the same size, the test will yield an interval that captures the true parameter
  10. 15. reject the null when the null is true
  11. 16. alternative is not equal to the null
  12. 18. probability that the statistic would take on that value or one more extreme, given the null is true
