APFIVE Confidence Intervals and Hypothesis Tests
All of the following statements about the relationship between confidence intervals and hypothesis tests are true except:
| Concept | Relationship |
|---|---|
| Confidence Interval | Range of plausible parameter values |
| Hypothesis Test | Evaluates a specific null value for a parameter |
A
A confidence interval provides a range of plausible values for the population parameter.
B
If repeated samples are taken, approximately 95% of the intervals computed would contain the true population parameter.
C
A confidence interval that does not contain the null parameter value indicates significance at the corresponding level in a two-tailed test.
D
If a 95% confidence interval for a parameter includes the null value, the corresponding two-tailed hypothesis test will reject the null hypothesis.
