Most women who have had a mastectomy can have breast reconstruction surgery.The reconstruction surgery can be performed at the same time as the mastectomy,an immediate reconstruction,or after the patient has healed from the mastectomy,second surgery reconstruction.Some women opt not to have reconstruction surgery.The table shows the percentages of women's choices regarding reconstruction for three age categories.A graphical display of the conditional distributions of reconstruction choice by age is given.

Does there appear to be an association between reconstruction choice and age? Explain.
A)No.The number of women over 50 who were included in these data was probably higher than the number who were under 35.Using this assumption,there is not enough evidence to show an association between reconstruction choice and age.
B)Yes.A higher percentage of older women,especially over 50,who have had mastectomies choose not to have reconstruction surgery.Likewise,a higher percentage of younger patients choose to have immediate reconstruction.It appears that as the age of women having mastectomies increases,the importance of having reconstructive breast surgery decreases.
C)No.The percentages of women who have had mastectomies who choose to have second surgery reconstruction do not vary significantly.There is not enough evidence to show an association between reconstruction choice and age.
D)No.In all age groups,most women want reconstruction surgery.
E)Yes.A higher percentage of older women,especially over 50,who have had mastectomies choose to have second surgery reconstruction.It appears that as the age of women having mastectomies increases,the importance of having reconstructive breast surgery increases.

The graphical display of the conditional distributions shows that the percentage of women who choose not to have reconstruction surgery increases with age, while the percentage of those who opt for immediate reconstruction decreases with age. This suggests that there is an association between age and reconstruction choice, with older women being less likely to have reconstruction surgery.
