Need to understand how to solve using excel or megastat 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 35 23 28 $50,000 ≤ Income < $100,000 56 45 43 $100,000 ≤ Income < $150,000 45 20 34 Income ≥ $150,000 34 17 20 The p-value for this hypothesis test is ________.
