20 1 1 Guangdong college entrance examination science mathematics fill-in-the-blank question that height question.
Because the son's height is related to his father, let his son's height be Y and his father's height be X. According to the data table:

X 173 170 176

Y 170 176 182

Substituting the regression equation (given at the beginning of the test paper), we can get: b= 1 a=3.

Y=X+3。

When X= 182 and Y= 185, fill in 185.
