Suppose we have a linear equation through the origin

(Exercise 11.28) μ = βx.

1. Estimate the regression line passing through the origin for the following data:

Y|x 2. Suppose it is not known whether the true regression should pass through the origin. Estimate the linear model μ = β +

β x and test the hypothesis that β = 0, at the 0.10 level of significance, against the alternative that β ≠ 0.
