Across
- 2. if it states that the parameter is different from the null hypotheses value (not equal to null hypothesis)
- 6. if it states that a parameter if larger or smaller than the null hypothesis value (greater/less than or equal to null hypothesis)
- 7. a procedure for comparing observed data with a claim (hypothesis) whose truth we want to assess
- 8. if the p-value is smaller than a specified value α
- 9. H0- a statement of "no difference"; we perform the test to assess the strength of the evidence against it
- 11. if the p-value is greater than or equal to α
- 12. what you have to check in order to perform a confidence interval
- 14. estimate +/- margin of error
- 16. if we reject H0 when it is in fact try
- 17. how close the estimate tends to be to the unknown parameter
- 19. if we fail to reject H0 when it is actually false
Down
- 1. when the standard deviation of a statistic is estimated
- 3. Ha- the claim we hope or suspect to be true instead of the null hypothesis
- 4. our "best guess" at the value of an unknown parameter
- 5. a statistic that provides and estimate of the pop. parameter
- 10. a level C confidence interval for the mean μ
- 12. the success rate of the method that produces the interval
- 13. the probability that measures the strength of the evidence against a null hypothesis
- 15. n-1
- 18. when the population is non-Normal, especially for larger sample sizes
