6. A random sample of workers contains 120 men and 131 women. The sample average of men’s weekly earnings is $523.10 and the standard deviation is $68.10. The sample average of women’s weekly earnings is $485.10 and the standard deviation is $51.10. Using this data of men and women, a researcher estimates the following regression Earningsi = β0 + β1 × Femaei + ui where Femae, a variable that is equal to 1 if the person is female and 0 if the person is a male. Find the OLS estimates of β0 and β1 and their corresponding standard errors
