AP Stat Vocab. Ch. 8 and 9*
Across
- 5. fail to reject Ho when Ho is false
- 7. statistic that provides an estimate for pop. parameter
- 8. an inference procedure is called this if the prob. calculations involved in that procedure remain fairly accurate when a condition for using the procedure is violated
- 9. probability that the statistic would take a value as extreme or more than the one actually observed, assuming Ho is true
- 11. used to specify a particular t distribution
- 14. we reject Ho when Ho is true
- 15. data are ( ) if the p-value is smaller than alpha
- 18. when the standard deviation of a statistic is estimated from the data
- 20. random, normal, independent
Down
- 1. tells how close the estimate is to the unk. parameter
- 2. claim tested by a statistical test
- 3. assesses the evidence provided by data against a null hypothesis in favor of an alternative hypothesis
- 4. claim about the population that we are trying to find evidence for
- 6. estimate +/- margin of error
- 10. value of the point estimator from a sample
- 12. alternative hypothesis is ( ) if it states that the parameter is different than the null value
- 13. probability that the test will reject Ho at a chosen alpha level when the specified alternative value of the parameter is true
- 16. gives the success rate of the method for calculating the confidence interval
- 17. similar but different than the z distribution, has more area in the tails
- 19. alternative hypothesis is ( ) if it states that a parameter is larger or smaller than the null value
