Across
- 2. occurs if we fail to reject the null hypothesis when it is actually false
- 4. this term indicates that the probability calculations will remain fairly accurate even when a condition for use of the procedure is violated
- 7. how many items in your sample are allowed to vary
- 9. a fixed value that we regard as decisive, written as the Greek letter alpha
- 10. when the standard deviation of a statistic is estimated from the data (s/√n)
- 12. a probability distribution that arises in the problem of estimating the mean of a normally distributed population when the sample size is small
- 13. says that a parameter differs from its null hypothesis value in a specific direction or in either direction
- 15. if the population parameter differs in a specific direction (larger or smaller) it is said to be ___-_____.
- 17. an interval of plausible values for a certain parameter
- 18. measures the ability of the test to detect an alternative value of the parameter
- 19. the range of values above and below the point estimate
- 20. the z-score that is paired with a confidence level (C%)
Down
- 1. using sample data to draw a conclusion about a population parameter
- 3. the success rate of the method used to construct the confidence interval
- 5. a single number based on sample data that represents a plausible value for that parameter
- 6. often a statement of no change or no difference in a population parameter
- 8. assesses the evidence provided by data against a null hypothesis in favor of an alternative hypothesis
- 11. when the p-value is smaller than the significance level the data is said to be ____________.
- 14. if the population parameter differs in either direction it is said to be ___-_____.
- 16. occurs if we reject the null hypothesis when it is actually true
