Question: A multiple regression of y on a constant x 1 and x 2 produces the following results: y = 4 + 0.4x 1 + 0.9x

A multiple regression of y on a constant x1and x2produces the following results: ŷ = 4 + 0.4x1+ 0.9x2, R2= 8/60, e'e = 520, n = 29,

[29 0 0 50 10 X'X = 10 80

Test the hypothesis that the two slopes sum to 1.

[29 0 0 50 10 X'X = 10 80
