Across
- 2. The probability that measures the strength of the evidence against H0 and in favor of Ha
- 5. shows how close we believe our guess is based on the variability of the estimate
- 7. approaches the standard Normal distribution as the number of degrees of freedom increases
- 11. the result of when the standard deviation of a statistic is estimated from data
- 13. the alternative hypothesis is ___ if it states that a parameter is larger than the null hypothesis value or if it states that the parameter is smaller than the null value
- 15. the claim we seek evidence against
- 16. If we reject H0 when H0 is true, we have committed a ___
- 17. If the P-value is smaller than alpha, we say that the results of a study are ___
- 18. a multiplier that makes the interval wide enough to have the stated capture rate
Down
- 1. the claim we hope or suspect to be true
- 2. a statistic that provides an estimate of a population parameter
- 3. a formal procedure for using observed data to decide between two competing claims (also called hypotheses)
- 4. the value of that statistic from a sample
- 6. gives the overall success rate of the method for calculating the confidence interval
- 8. the alternative hypothesis is ___ if it states that the parameter is different from the null hypothesis value (it could be either larger or smaller)
- 9. describes how far x will typically be from μ in repeated SRSs of size n
- 10. when conditions are met, a C% confidence interval for the mean μ is given by the
- 12. a fixed value that we regard as decisive
- 14. If we fail to reject H0 when Ha is true, we have committed a ___
