  1. 2. Observations from the population have a normal distribution or the sample size is large (n>30)
  2. 4. The range of values above and below the point estimate
  3. 6. Assesses the evidence provided by data against a null hypothesis in favor of an alternative hypothesis
  4. 8. gives the overall success rate of the method for calculating the confidence interval
  5. 11. A single number based on sample data (a statistic) that represents a plausible value for that paramter
  6. 12. Is an interval of plausible values for that parameter
  7. 14. if it states that a parameter is larger than the null hypothesis value or it states that the parameter is smaller than the null value.
  8. 15. Says that a parameter differs from its null hypothesis value in a specific direction
  9. 19. probability computed supposing the null hypothesis to be true, that the statistic will take a value at least as extreme as that actually observed in the direction specified by the alternative hypothesis.
  10. 20. If it states that the parameter is different from the null hypothesis value, either larger or smaller.
  11. 21. Is the success rate of the method used to construct the confidence interval

  1. 1. We are c% confident that the interval from ___ to ___ captures the actual value of the population parameter
  2. 3. when the p-value is smaller than the significance level, the data is ________.
  3. 5. measures how far a sample statistic diverges from what we would expect if the null hypothesis were true.
  4. 7. occurs if we fail to reject the null hypothesis when it is actually false.
  5. 9. measures the ability of the test to detect an alternative value of the parameter.
  6. 10. When o is known and either the sample size n is large or the population distribution is normal
  7. 13. A statement of no change or no difference
  8. 16. occurs if we reject the null hypothesis when it is in fact true.
  9. 17. If the probability calculations involved in the procedure remain fairly accurate when a condition for using the procedure is violated
  10. 18. When the population is at least 10 times greater than the sample size
