Student loans: In an article from September 13, 2010, titled “Student Loan Default Rates Increase,” the website ed. gov analyzes trends in default rates for student loans over time. For the year 2008, the default rate for graduates was 7%. This means that 7% of the students who graduated in 2008 and had student loans did not make payments to repay those loans. Suppose we select 3 random samples of 1000 students each from this population of graduates from 2008. Which of the following is most likely to occur with the three samples? Group of answer choices The number who have defaulted will equal 7% in each of the three samples. The number who have defaulted will increase as we select samples because the default rates are increasing. The number who have defaulted will vary in each sample due to the random selection of graduates. The number who have defaulted will average 7% across the three samples.
