Question 1 from chapter 10: "Explain how economists use
regression analysis to measure discrimination. Is a significant
coefficient on the attribute (e.g. race/gender/ethnicity/sexual
orientation/beauty/weight/color/religion/etc. variable proof of the
existence of discrimination? Explain."
1. Please write out the basic (i.e., single-predictor)
regression equation.
Y=...
2. If the unstandardized regression coefficient (the slope of y
on x) in a basic, single-predictor regression was found to be
b_yx=-0.40, what is the interpretation of "b_yx=-0.40"?
3. If the regression constant (the y intercept) in a basic,
single-predictor regression was found to be a=0.80, what is the
interpretation of "a=0.80"?

Fifteen hundred adult males working for Locheed Aircraft are
recruited to participate in a study of coronary heart disease.
Every 3 years they are examined for new occurrences of this
disease. Coronary heart disease rates are compared among groups
defined by personal characteristics as they were recorded at the
beginning of the study.
A random sample of middle-age sedentary females...
how can you use regression analysis to make a decision as a
cashier? Include a description of the decision, what would be the
independent and dependent variables, and how data could ideally be
collected to calculate the regression equation.
