Question
- Which one of the following statements is true?
- The sample proportion is a parameter.
- A confidence interval is computed in order to estimate an unknown sample statistic.
- The margin of error is affected by the size of the sample proportion.
- If you construct a confidence interval for a population proportion and the interval ends up being from 0.48 to 0.59, this means the population proportion is definitely larger than 0.50.
- If a 95% confidence interval is given as 0.32 to 0.46, this means the sample proportion must be 0.38.

Mary selects a random sample of 50 families to survey, and she observes a sample proportion of 0.10. David selects a random sample of 100 families to survey, and he also observes a sample proportion of 0.10. Mary and David each use their sample data to construct a 95% confidence interval. Who will have the more narrow confidence interval? A. Both intervals will have the same width since the sample proportions are the same. B. Both intervals will have the same width since the level of confidence is the same for each interval. C. Both intervals will have the same width since the sample proportions are the same and the level of confidence is the same for each interval. D. Mary's interval will be more narrow than David's interval. E. David's interval will be more narrow than Mary's interval.arrow_forward
