To determine if there is an association between gender and reading habits, 270 adults are randomly sampled from across the United States and asked the following question: “How often do you read a book outside of work or school: regularly, sometimes, or never?” The results are summarized in the following table: OBSERVED READING HABITS Regularly Sometimes Never Total Male 42 72 10 124 Female 72 74 7 146 Total 107 146 17 270 A)Suppose the chi-square test statistic is 3.7329254 with 2 degrees of freedom. Using the chi-square table, what is the p-value for this test? B)Suppose the p-value is 0.11. At the a = 0.05 level, what conclusion should be made?
