Choose the correct terms below: 1. If you increase the confidence level you would expect the confidence interval to be Wider Narrower because to be more confident you would need to include the same number of less more possible values of the population parameter. 2. If you decrease the confidence level you would expect the confidence interval to be narrower wider because to be more confident you would need to include more the same number of less possible values of the population parameter. 3. True or False? Suppose a confidence interval actually contains the population parameter. The same data was used to make a confidence interval with a larger confidence interval you can conclude that the new interval will also include the true population parameter. True False 4. True or False? Suppose a confidence interval actually contains the population parameter. The same data was used to make a confidence interval with a smaller confidence interval you can conclude that the new interval will also include the true population parameter. True False 5. True or False? If we repeat the study and make a new confidence interval it will be centered at the same value as the previous confidence interval. True False 6. A confidence interval with a larger sample size will be narrower wider than a confidence interval with a smaller sample size because the standard deviation of the sampling distribution population distribution is the same. larger. smaller.
Choose the correct terms below:
1. If you increase the confidence level you would expect the confidence interval to be
- Wider
- Narrower
because to be more confident you would need to include
- the same number of
- less
- more
possible values of the population parameter.
2. If you decrease the confidence level you would expect the confidence interval to be
- narrower
- wider
because to be more confident you would need to include
- more
- the same number of
- less
possible values of the population parameter.
3. True or False? Suppose a confidence interval actually contains the population parameter. The same data was used to make a confidence interval with a larger confidence interval you can conclude that the new interval will also include the true population parameter.
- True
- False
4. True or False? Suppose a confidence interval actually contains the population parameter. The same data was used to make a confidence interval with a smaller confidence interval you can conclude that the new interval will also include the true population parameter.
- True
- False
5. True or False? If we repeat the study and make a new confidence interval it will be centered at the same value as the previous confidence interval.
- True
- False
6. A confidence interval with a larger
- narrower
- wider
than a confidence interval with a smaller sample size because the standard deviation of the
- sampling distribution
- population distribution
is
- the same.
- larger.
- smaller.
