Across
- 2. _____ sided alternative hypothesis- states that the parameter is different from the null hypothesis value
- 4. a margin of ______tells how close the estimate tends to be to the unknown parameter in repeated random sampling.
- 8. a t ______ has a different shape than the standard Normal curve: still symmetric with a single peak at 0, but with much more area in the tails
- 10. the p value is Statistically ___ when it is smaller than the alpha
- 11. _____ hypothesis is The claim about the population that we are trying to find evidence
- 13. one-sample t ______- used when σ is unknown
- 14. a point ______ is a statistic that provides an estimate of a population parameter
- 16. the standard error of the sample _____describes how far will be from μ, on average, in repeated SRSs of size n.
- 17. _____of freedom- used in t distributions n-1
- 19. ____ data- Study designs that involve making two observations on the same individual
- 20. the p____ is the probability that the statistic would take a value as extreme as or more extreme than the one actually observed
Down
- 1. the probability that the test will reject H0 at a chosen significance level α when the specified alternative value of the parameter is true.
- 3. a _____ level gives the overall success rate of the method for calculating the confidence interval
- 5. ______test- a formal procedure for comparing observed data with a claim whose truth we want to assess
- 6. _____-sample z interval for a population proportion- the replaced the standard deviation of p with the formula for its standard error
- 7. ________ procedures are the probability calculations involved in that procedure remain fairly accurate when a condition for using the procedure is violated.
- 9. One-____ alternative hypothesis 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
- 12. ______ error is the result when the standard deviation of a statistic is estimated from data
- 15. a confidence _______uses sample data to estimate an unknown population parameter with an indication of how precise the estimate is and of how confident we are that the result is correct.
- 18. _____hypothesis is the claim tested by a statistical test
