Across
- 3. decision about h null
- 9. hypothesis sample observations are influenced by some non-random cause
- 10. no variation exists between variables
- 13. the radius (or half the width)of the confidence interval for that statistic
- 15. involves the use of sample data to calculate a single value
- 19. population
Down
- 1. h null is true but rejected
- 2. x bar
- 4. z-score indicates how many standard deviations an element is from the mean
- 5. a theory
- 6. measures the accuracy with which a sample represents a population
- 7. use 2-prop Z interval
- 8. probability of type 2 error
- 11. 0.0729
- 12. 0.0075
- 14. use mean
