The following constants are obtained from measurements on length in mm. (X1), volume in c.c. (X2) and weight in gm. (X2) of 300 eggs : X, = 55-95 S, = 2-26 %3D 12 = 0-578 X, = 51-48 %3D S, = 4-39 %3D 13 = 0-581 %3D X3 = 56 03 S3 = 4.41 = 0-974 %3D Obtain the linear regression equation of egg weight on egg length and egg volume. Hence, estimate the weight of an egg whose length is 58 mm. and volume is 52-5 c.c.
