Testing a Claim

5. a point on the test distribution that is compared to the test statistic to determine whether to reject the null hypothesis
9. gives overall success rate of the method for calculating the confidence interval
10. be sure to check this condition before calculating a confidence interval
13. if the P-Value is smaller then alpha
14. the data cones from a well designed random sample or a randomized experiment
16. result of the standard deviation of a statistic is estimated from the data
18. the condition that is crucial for reference
19. if it states that the parameter is different than the null hypothesis
20. the probability that the test will reject the null at a chosen significance level when the specified alternative value of a parameter is true

1. statement of "no difference"
2. gives interval of plausible values for a parameter
3. statistic that provides estimate of a population
4. if it states that a parameter is larger than the null hypothesis value
6. the claim about the population that we are trying to find evidence for
7. measures how far a sample statistic diverges from what we would expect if the hypothesis were true
8. helps you determine significance
11. the incorrect rejection of a true null hypothesis (a "false positive"
12. value of statistic from a sample
15. an amount that is allowed for incase of miscalculation or change of circumstances
17. incorrectly retaining a false null hypothesis (a "false negative"
