Suppose Bank of America would like to investigate if the credit score and income level of an individual are independent of one another. Bank of America selected a random sample of 400 adults and asked them to report their credit score range and their income range. The following contingency table presents these results. Credit Score class Less than 650 650-750 More than 750 Income < $50,000 31 21 21 $50,000 s Income < $100,000 79 57 45 $100,000 s Income < $150,000 Income 2 $150,000 54 24 22 21 12 13 The p-value for this hypothesis test is
