Across
- 5. the sample statistic when used to estimate the corresponding population parameter
- 6. States that a parameter is larger than the null hypothesis value or if it states that the parameter is smaller than the null value.
- 8. in a confidence interval the extent of the interval on either side of the observed statistic value
- 9. Process that states parameter, checks conditions, calculations, and interprets.
- 11. The claim about the population that we are trying to find evidence for.
- 12. The claim we weigh evidence against in a statistical test. Often a statement of "no difference."
- 13. Used instead of a z-score when the population standard deviation is unknown.
- 14. A range of values used to estimate a variable of interest.
- 17. if the p-value is smaller than the alpha at the given level.
- 19. the probability that the test will reject the null hypothesis at a chosen significance level alpha when the specified alternative value of the parameter is true
- 20. things we must verify before calculations (normal, random, and independent)
Down
- 1. we fail to reject the null hypothesis when the alternative hypothesis is true
- 2. If the probability calculations involved in procedure remain fairly accurate when a condition for using the procedure is violated.
- 3. A statistical property of a large family of distributions. Equals n-1.
- 4. States that the parameter is different from the null hypothesis value (it could be either larger or smaller).
- 7. When the standard deviation of a statistic is estimated from data.
- 10. The probability, computed assuming Ho is true, that the statistic (such as p-hat or x-bar) would take a value as extreme as or more extreme than the one actually observed.
- 15. Level of confidence that the interval provides (90%, 95%, 99%)
- 16. if we reject the null hypothesis when it is in fact true
- 18. measures how far a sample statistic diverges from what we would expect if the null hypothesis were true
