Suppose we have a linear equation through the origin
Chapter , Problem 7.33(choose chapter or problem)
Suppose we have a linear equation through the origin (Exercise 7.28) Y |x = x. (a) Estimate the regression line passing through the origin for the following data: x 0.5 1.5 3.2 4.2 5.1 6.5 y 1.3 3.4 6.7 8.0 10.0 13.2 (b) Suppose it is not known whether the true regression should pass through the origin. Estimate the linear model Y |x = 0 + 1x and test the hypothesis that 0 = 0, at the 0.10 level of significance, against the alternative that 0 = 0.
