Mutual funds are a popular way of investing in the stock market. A financial analyst wanted to determine the effect income had on ownership of mutual funds and whether the relationship had changed from four years earlier. She took a random sample of adults 25 years of age and older and asked each person whether he or she owned mutual funds (No = 1 and Yes = 2) and to report the annual household income. The categories are

1. Less than $25,000

2. $25,000 to $34,999

3. $35,000 to $49,999

4. $50,000 to $74,999

5. $75,000 to $100,000

6. More than $100,000

Can we infer from the data that household income and ownership of mutual funds are related?
