  1. 4. the probability, computed supposing H0 to be true, that the statistic will take a value at least as extreme as that actually observed in the direction specified by Ha
  2. 6. gets smaller as the confidence level C decreases and/or the sample size n increases
  3. 8. when using this type of data, you must first find the difference within each pair and produce a single sample before using one-sample t procedures
  4. 9. the data is _____________ ______________ if the p-value is smaller than the specified alpha value
  5. 14. tells us how likely it is that the method we are using will produce an interval that captures the population parameter if we use it many times
  6. 15. t procedures are not robust against these
  7. 16. found by adding and subtracting the margin of error to/from the statistic value
  8. 17. a reasonable or believable value based on the data
  9. 18. when dealing with means, this theorem allows for the normal condition to be met as long as n≥30
  10. 19. assesses the evidence provided by data against a null hypothesis H0 in favor of an alternative hypothesis Ha
Down
  1. 1. when we don't know p, we replace it with the sample proportion p hat and find the ________ ________
  2. 2. occurs if we fail to reject H0 when it is actually false (Use Roman Numerals)
  3. 3. this is often a statement of no change or no difference
  4. 5. the probability that the test will reject H0 when the alternative is true
  5. 7. found by the equation n-1
  6. 8. a statistic that provides an estimate of a population parameter
  7. 10. says that a parameter different from its null hypothesis value
  8. 11. the probability of committing a type 1 error
  9. 12. when using proportions, np and n(1-p) must be at least 10 to satisfy the ___________ condition
  10. 13. occurs if we reject H0 when it is in fact true (Use Roman Numeral)
