Step-by-Step Solution

Verified

Answer

No. The sample is not representative.

1Step 1. Given information.

The given statement says that the researcher surveyed a sample of 250 students at Yale.

We have to explain if the given sample is representative or not.

2Step 2. Identify the sample.

This sample that is collected by the researcher is not a representative sample.

The reason is the researcher surveyed a sample of only 250 students at Yale.

However, he wants to calculate the average salary of college students' parents. Because the sample is not representing the whole population of students who go to college.

Therefore, the sample is not a representative sample.
