Across
- 6. when the value of a variable is determined by a chance event
- 7. occurs when Ho is not rejected when Ho is false
- 11. when the p-value is less than the chosen significance level a
- 15. assesses the evidence provided by data about some claim concerning a population
- 16. two events are this when the occurence of one does not effect the probability of the occurence of the other
- 17. found by subtracting 1 from n
- 18. tells how close the estimate tends to be to the unknown parameter in repeated random sampling
- 19. sampling distribution of the t statistic
Down
- 1. occurs if Ho is rejected when it is true
- 2. claim tested by a statistival test
- 3. measures how far a sample statistic diverges from what we would expect if the null hypothesis were true
- 4. a statistic that provides an estimate of a population parameter
- 5. the probability that the test will reject Ho at a chosen significance level a when the specified alternative value of the parameter is true
- 8. estimate the value of a point estimator
- 9. probability that the statistic would take a value as extreme or more extreme than the one actually observed
- 10. an interval calculated from sample data
- 11. the result when the atandard deviation of a statistic is estimated from data
- 12. the claim about the population that we are trying to find evidence for
- 13. the success rate of the method that produces the confidence interval in C% of all samples
- 14. study designs that involve making two observations on the same individual
