In Example 12.4 and Table 12.5, we presented data from Australia showing that the likelihood of couples separating depended on whether the wife’s parents had been divorced. For this exercise, we consider the likelihood of the couple separating based on whether the husband’s parents had been divorced. Table 12.11 shows the results for this situation.
a. What is the risk of a couple separating if the husband’s parents had been divorced?
b. What is the risk of a couple separating if the husband’s parents had not been divorced?
c. Find the relative risk of a couple separating under the two conditions. Write your answer in a sentence that would be understood by someone with no training in statistics.
