Textbook Question
Chapter 10, Problem 65P
Cancer
A topic of current interest is whether abortion is a risk factor for breast cancer. One issue is whether women who have had abortions are comparable to women who have not had abortions in terms of other breast-cancer risk factors. One of the best-known breast-cancer risk factors is parity (i.e., number of children), with parous women with many children having about a 30% lower risk of breast cancer than nulliparous women (i.e., women with no children). Hence, it is important to assess whether the parity distributions of women with and without previous abortions are comparable. The data in Table 10.30 were obtained from the Nurses’ Health Study on this issue.
TABLE 10.30 Parity distribution of women with abortions and women without abortions
What test can be performed to compare the parity distribution of women with and without induced abortions?
