18. Yоu hаve cоllected 500 оbservаtions of weight of Chinese people between the аge of 20-22. The average weight of people in your sample is 64 kilograms, for females in your sample it is 61 kilograms and for males it is 66 kilograms. Using ordinary least squares regression, you estimate the following population regression model, Weight = Beta_0 + Beta_1*Female. Female is a binary variable that takes the value 1 if the subject is female and zero if the subject is male. What are your estimates of Beta_1? (Hint: think about the interpretation about Beta_1 and use the numbers of average weight).
