From heights (x;) in inches, weights (x2) in kg. and ages (x) in years of a group of students, the foilowing means, variances and correlation cnefficients were obtained : X, = 40, X = 50, x3 - 20 ; s; = 3, s2 = 4, s3 - 2 ; r;2= 0-4, r = 0-5, r3= 0-25, where x, is the mean of x;, 5? is ihe variance of x; and r; is correlation coefficient between x, and x; for i, j - 1, 2, 3. Finci the multiple regression equation of x3 on (x; and x) and estimate the value of x when X, = 43 inches and x, = 54 kg.
