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

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
