AP Stat Ch 8 and 9 Vocabulary
Across
- 4. if a parameter is different from the null value (either larger or smaller)
- 5. the standard deviation of a statistic estimated from the data
- 6. error if we fail to reject Ho when Ho is false
- 7. describes a value of a parameter if it is reasonable based on data
- 8. how close the estimate tends to be to the unknown parameter
- 9. a formal procedure for comparing observed data with a claim
- 11. the claim about the population we are trying to find evidence for
- 13. what you are checking for when you make sure the population is 10x the sample size
- 14. gives an interval of plausible values for a parameter
- 16. of the sample mean where sx is the sample standard deviation
- 19. if a parameter is larger or smaller than the null value
- 20. gives the overall success rate of the confidence interval
Down
- 1. a claim tested by a statistical test
- 2. use for t distribution with n-1
- 3. statistic that provides an estimate of a population parameter
- 10. if the p value is smaller than alpha
- 12. the probability that the statistic would take a value as extreme or more extreme than the one actually observed
- 15. the probability calculations remain accurate when a condition is violated
- 17. the probability that the test will reject Ho at a chosen significance level when the specified alternative value of the parameter is true
- 18. error if we reject Ho when Ho is true
