An economist believes that the wage difference between black females and nonblack males is $200 in favor of nonblack males (in other words, the economist believes that black females make $200 less than nonblack males). We want to perform a test on this claim. What is the rejection rule for this test?

Wages, gender and race. You are interested in the relationship between wages, race and gender. You have the following econometric model: wage = Bo + B1 * female + B2 * black + u where the variable wage is the monthly wage in dollars, female is a gender dummy variable (equal to 1 for females and 0 otherwise), black is a race dummy variable equal to 1 for blacks and zero otherwise, and u is an error term. Using 4,137 observations, the following equation was estimated by OLS: wage = 1028.10 - 45.09 * female - 169.81 * black (6.29) (4.29) (12.71) where the numbers in parentheses (below the coefficients) are the standard errors
