Question

Consider a hypothetical regression predicting if someone will be married or not by the age of 40, MARRIED? (1 means this person is married by the age of 40 and 0 means this person is not married by the age of 40).

The regression is as follows (all variables are statistically significant):

MARRIED? = 0.2 + 0.03*EDUCATION - 0.01*BMI

Where EDUCATION is the number of years of education someone's had and BMI is their body mass index.

Suppose someone had 20 years of education and a BMI of 25. What is the predicted value of MARRIAGE?

a  

0, because the calculated value is 0.35 so we round down. 

b  

0.55, which makes sense even though MARRIED? can only be a zero or one.

c  

0.35, which makes sense even though MARRIED? can only be a zero or one

d  

Calculating a predicted value should not be done here because the dependent variable is a dummy variable.

e  

1, because the calculated value is 0.55 so we round up.
