A social scientist wants to determine whether the marital status (divorced or not divorced) of U.S. men is independent of their religious affiliation (or lack thereof). A sample of 500 U.S. men is surveyed, and the results are tabulated as shown in Table 13.7.

Table 13.7 Survey Results (observed Counts), Example 13.3 Religious Affiliation A B C D None Totals Marital Status Divorced 39 19 12 28 18 116 Married, never divorced 172 61 44 70 37 384 Totals 211 80 56 98 55 500 Data Set: MARREL

a. Test to see whether there is sufficient evidence to indicate that the marital status of men who have been or are currently married is dependent on religious affiliation.

Take a = .01.

b. Graph the data and describe the patterns revealed. Is the result of the test supported by the graph?
