2.20 Consider a multiple regression model with k regressors. Show that the test statistic for significance of regression can be written as (1 -#)/(*-* - 1) Suppose that n = 20, k = 4, and R2 = 0.90. If a = 0.05, what conclusion would you draw about the relationship between y and the four regressors?
