Chapter 8 & 9 Vocabulary

5. value of statistic from a sample
7. if it states that a parameters larger than the null hypothesis value
8. statistic that provides estimate of the population
10. the claim about the population that we are trying to find evidence for
11. helps you determine the significance of your results
12. the data come from a well designed random sample or randomized experiment
13. if it states that the parameter is different from the null hypothesis value
15. the probability that the test will reject Ho at a chosen significance level when the specified alternative value of the parameter is true
18. be sure to check this condition before calculating a confidence interval;
19. is incorrectly retaining a false null hypothesis ("a false negative")
20. result of the standard deviation of a statistic is estimated from the data

1. gives overall success rate of a method for calculating the confidence interval
2. statement of "no difference"
3. if the p-value is smaller than alpha
4. measure how far a sample statistic diverges from what we would expect if the null hypothesis were true
6. is the incorrect rejection of a true null hypothesis ("a false positive")
9. gives interval of plausible values for a parameter
14. the condition that is crucial for doing reference
16. an amount that is allowed for in case of miscalculation or change of circumstances
17. is a point on the test distribution that is compared to the test statistic to determine whether to reject the null hypothesis
