Across
- 4. probability of a type two error
- 6. an interval of plausible values for an unknown parameter value
- 7. a function that represents the distribution of many random variables as a symmetrical bell shaped graph
- 11. used when finding the p-value for a proportion
- 13. the statement we seek evidence against
- 14. when the standard deviation of a statistic is estimated from data the result is called
- 16. we fail to reject the null when it is false
- 18. a subset of individuals chosen from a larger set in which each individual is chosen randomly and entirely by chance
- 19. probability of a type one error
- 20. gives the overall success rate of the method for calculating the confidence interval
Down
- 1. probability the measures the strength of the evidence against the null and in favor of the alternative
- 2. when the p-value is smaller than alpha
- 3. used when finding the p-value for a mean
- 5. a statistic measured from a sample
- 8. we reject the null when it is true
- 9. the statement of inequality opposing original claim the statement we are trying to find evidence in favor of
- 10. assures that the number of success and failures is above 10 to be able to be normally distributed
- 12. distance from point estimate for the interval
- 15. are essentially cut-off values that define reigons where the test statistic is unlikeley to lie
- 17. the number of values in the final calculation of a statistic that are free to vary
