Across
- 3. where you identify the null and the alternative
- 5. Test used to find the p value for a proportion on a significance test
- 8. a statistic measured from a sample
- 9. cut off values that define regions where the test is unlikely to lie
- 10. test used for proportions on problems dealing with confidence intervals
- 12. an interval of plausible values for an unknown parameter value
- 13. value used to judge whether a test is statistically significant
- 14. the null
- 15. condition in which n must be greater than 30 or normal is stated
- 19. the formula is the square root of P(1-P)/n
- 20. test used for finding the p value on a mean problem
Down
- 1. numerical measurement that describes a value's relationship to the mean of a group of values
- 2. the alternative
- 4. a piece of statistical information you get from a handful of items
- 6. reject Ho when it is true
- 7. the 10% rule
- 11. fail to reject Ho when it is not true
- 16. the condition to check if the sample is properly randomized
- 17. must be less than alpha in order to reject the null
- 18. distance from point estimate for the interval
- 19. size equation is z critical x standard deviation / margin of error
