一个已婚女性的群体，有变量 educ = years of education  ；   lfp = 1 if in the labor force; 0 otherwise ； kidslt6 = number of kids younger than 6 years old

Calculate the average years of education both for women who work and for women who do not work. Are women who work more likely to have kids under 6 than women who do not work?

这个该怎么输命令呢
