AP Statistics Ch8 & Ch9 Terms
Across
- 4. the probability, computed supposing H0 to be true, that the statistic will take a value at least as extreme as that actually observed in the direction specified by Ha
- 6. gets smaller as the confidence level C decreases and/or the sample size n increases
- 8. when using this type of data, you must first find the difference within each pair and produce a single sample before using one-sample t procedures
- 9. the data is _____________ ______________ if the p-value is smaller than the specified alpha value
- 14. tells us how likely it is that the method we are using will produce an interval that captures the population parameter if we use it many times
- 15. t procedures are not robust against these
- 16. found by adding and subtracting the margin of error to/from the statistic value
- 17. a reasonable or believable value based on the data
- 18. when dealing with means, this theorem allows for the normal condition to be met as long as n≥30
- 19. assesses the evidence provided by data against a null hypothesis H0 in favor of an alternative hypothesis Ha
Down
- 1. when we don't know p, we replace it with the sample proportion p hat and find the ________ ________
- 2. occurs if we fail to reject H0 when it is actually false (Use Roman Numerals)
- 3. this is often a statement of no change or no difference
- 5. the probability that the test will reject H0 when the alternative is true
- 7. found by the equation n-1
- 8. a statistic that provides an estimate of a population parameter
- 10. says that a parameter different from its null hypothesis value
- 11. the probability of committing a type 1 error
- 12. when using proportions, np and n(1-p) must be at least 10 to satisfy the ___________ condition
- 13. occurs if we reject H0 when it is in fact true (Use Roman Numeral)
