New Housing Policy
The university administrators have decided to require all undergraduates to live on campus. This is because many beds have been vacated since senior students have moved out of the campus. Demanding all undergraduates to live on campus can help increase the school’s income. On the other hand, school activities will become more accessible if students could live on campus. If approved by a vote of the administration, the new requirement will become effective in the fal semester.
Question: The woman expresses her opinion towards the university’s decision to require all students to live on campus. State her opinion and explain the reasons she gives for holding that opinion.

Sampling Error
Often, students or employees will be asked to draw a conclusion from a huge amount of data. That’s when a sample is introduced. When a sample is accurate, it can represent the whole group. But when it is wrong, sampling error would occur. In statistics, sampling error or estimation error is caused by observing a single sample instead of the whole population. Sampling error can be found by subtracting the value of a parameter from the value of a statistic. Generally, there are two methods of reducing sampling error: increasing the sample size, and ensuring that the sample can adequately represent the entire population.
Question: The professor uses one experiment to illustrate the definition of "sampling error". Explain how this example is related to the reading passage.
