Chapter 8 and 9 Vocab

2. is a multiplier that makes the interval wide enough to have the stated capture rate.
4. There s what disribution for every positive degrees of freedom
7. measures how far a sample statistic diverges from what we would expect if the null hypothesis HO were true, in standardized units.
10. If we reject HO when HO is true.
12. The claim about the population that we are trying to find evidence for.
15. When the standard deviation of a statistic is estimated from the data.
17. How large a difference between the null parameter value and the actual parameter value is important for us to detect.
18. The claim we weigh evidence against in a statistical test.
19. is a statistic that provides an estimate of a population parameter.
20. test against a specific alternative is the probability that the test will reject HO at a chosen significance level when the specified alternative value if the parameter is true.

1. what is needed for a confidence interval
3. give the overall success rate of the method for calculating the confidence interval.
5. When our P-value is less than the chosen alpha in a significance
6. Estimate the best guess for the value of a population parameter.
8. What we use to estimate parameter.
9. assesses the evidence provided by data against a null hypothesis.
11. The first condition for a problem.
13. If we fail to reject HO when HA is true.
14. The probability that measures the strength of the evidence against HO and in favor of HA.
16. the difference in the point estimate an the true parameter.
