The Number of Undergraduates at Johns Hopkins University Is Approximately

question 6

Multiple Choice

The number of undergraduates at Johns Hopkins University is approximately 2000,while the number at Ohio State University is approximately 40,000.Suppose,instead,that at both schools a simple random sample of about 3% of the undergraduates will be taken.What can we conclude about the sampling variability for the sample proportion from Johns Hopkins as compared to that from Ohio State?

• A)The sample proportion from Johns Hopkins will have less sampling variability than that from Ohio State.
• B)The sample proportion from Johns Hopkins will have more sampling variability than that from Ohio State.
• C)The sample proportion from Johns Hopkins will have about the same sampling variability as that from Ohio State.
• D)It is impossible to make any statements about the sampling variability of the two samples because the students surveyed were different.
