Statistics

4. a family of distributions that look identical to the normal distribution curve
8. Gives an interval of plausible values for a parameter.
9. the claim that we are trying to find evidence for in a significance test
12. np> 10 and n(1-p)>10
13. Occurs if we reject H0 when H0 is true
14. Specific value of a point estimator from a sample.
16. if the observed result is too unlikely to occur by just chance alone when the null hypothesis is true
18. Procedure for using observed data to decide between two competing claims
19. When the standard deviation of a statistic is estimated from data
20. The data coming from a well designed random sample or randomized experiment

1. the difference between the point estimate and the true paramater value
2. If the observed result is not very unlikely to occur when the null hypothesis is true
3. Fixed value a that we use as a cutoff for deciding whether an observed result is too unlikely to happen by chance alone when the null hypothesis is true
5. the number of independents pieces of information that went into calculating the estimate
6. An alternative hypothesis that states that a parameter is larger than the null hypothesis value
7. A srs of size n from any popluation with mean u and finite standdard deviation
10. Claim that we weight evidence against in a significance test.
11. Sucess rate of the method for calculating the confidence interval.
15. occurs if we fail to reject H0 when H0 is true
17. The probablity,computed assumsing H0 is true
