Homework Answers
Note: As we increases the sample size, the sampling distribution of the sample mean ( or sample proportion ) is approximately normal.

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%. Suppose that we select random samples from this population of graduates from 2008. For each sample we calculate the proportion who defaulted on their loans. What is the minimum sample size necessary for the sampling distribution to be approximately...
