I run a regression in stata with the following variables: wage = hourly wage married = dummy variable =1 for married, =0 for nonmarried  female = dummy variable =1 for female, =0 for male  tenure = number of years on the job  tenursq = tenure squared  My results are shown below:  Table 1. OLS Regression of Wage on Marital Status, Sex, and Tenure Variable Coefficient Std. Error t-value p-value Married (1 = married) 0.784 0.306 2.56 0.011 Female (1 = female) –1.976 0.293 –6.74 0.000 Tenure 0.278 0.052 5.31 0.000 Tenure² –0.0055 0.0019 –2.96 0.003 Constant 5.379 0.306 17.60 0.000 Model Statistics Number of observations: 526 Adjusted R-squared: 0.218 F-statistic: 37.51 (df = 4, 521)   Question: Based on the coefficient for married, what is the substantive interpretation?

From the prior regression, I decide to test whether there is an interaction between marital status and sex in my wage model.  Based on the results below, what is the reference category for the interaction?  Table 2.

During an annual physical examination, a 43-year-old patient states that she does not perform monthly breast self-examinations (BSEs). She tells the nurse that she believes that mammograms “do a much better job than I ever could to find a lump.” The nurse should explain to her that:
