5. assures that the number of success and failures is above 10 to be able to be normally distributed
7. probability of obtaining test results at least as extreme as the results actually observed
8. probability of a type one error
9. test hypotheses regarding population proportions
11. we fail to reject the null when it is false
13. gives the overall success rate of the method for calculating the confidence interval
15. involves the use of sample data to calculate a single value
17. When your p-value is less than or equal to your significance level
19. subset of a statistical population in which each member of the subset has an equal probability of being chosen
20. a range of values so defined that there is a specified probability that the value of a parameter lies within it

1. a function that represents the distribution of many random variables as a symmetrical bell shaped graph
2. probability that measures the strength of the evidence against the null and in favor
3. depend upon a test statistic, which is specific to the type of test and the significance level
4. refers to the maximum number of logically independent values
6. used to avoid bias and other unwanted effects
10. when the standard deviation of a statistic is estimated from data the result is called
12. used when finding the p value for a proportion
14. probability of a type two error
16. we reject the null when it is correct
18. amounting to nothing
