Aleast squares regression line was calculated to relate the length (cm) of newborn boys to their weight in kg. the line is weight equals negative 5.31 plus 0.1694 length. a newborn was 48 cm long and weighed 3 kg. according to the regression model, what was his residual?

0.1788

Step-by-step explanation:

The regression equation relates the length of newborn to their weight, in kg.

The equation is

Where

w is weight in kg

l is length in cm

The residual is the difference in observed value and predicted value

The observed value is 3kg . Now let's find the predicted value by plugging in 48 into the equation (in l):

Residual = 3 - 2.8212 = 0.1788
