Across
- 2. to increase the power of a test we can, increase the sample size, pick alternative further from the null, or increase ___ level
- 4. a statement about a parameter
- 5. a procedure for comparing observed data with a claim whose truth we want to assess
- 7. sampling distribution is approximately normal (condition for confidence interval)
- 8. ___% of all possible samples of size___ from the population will result in an interval that captures the unknown parameter. (interpretation)
- 9. State, Plan, Do, Conclude
- 10. data from a well-designed random sample or randomized experiment (condition for confidence interval)
- 13. a single estimate of a population parameter (a statistic from a sample)
- 15. We fail to reject the null when the null is false
- 17. ___ always refer to a population, not to a sample
- 18. the claim about the population that we are trying to find evidence for
Down
- 1. depends on the critical value and the standard deviation of the statistic
- 3. the probability of a test rejecting the null when the alternative is true
- 4. We are ___% confident that the interval from __to__ captures the actual value of the (parameter in context)
- 6. when the standard deviation of a statistic is estimated from data the results are called the ____ of the statistic.
- 11. is often a statement of "no difference"
- 12. this value is NEVER negative
- 14. the 10% condition (condition for confidence interval)
- 15. We reject the null when the null is true
- 16. the probability of the statistic value being as extreme or more extreme than the actual observed value
