Only part e) please
For part e
The answers for (i,ii & iii) are calculated through one formula as below
e i = 7.03
e ii = 16.97
CI = (7.03, 16.97)
All calculations are done with 95% confidence interval and 5% level of significance (alpha)

top Suppose that a researcher, using wage data on 230 randomly selected male workers and 258 fermale workers, estimates the OLS regression 4 Wage 11.518 +1.950 x Male, R 0,04, SER = 3.9, (0.2116) (0.3312) where Wage is measured in dollars per hour and Male is a binary variable that is equal to 1 if the person is a male and 0if the person is a female. Define the wage gender gap as the difference in mean earnings between men...
